What Is The Meaning Of The Solar Constant Quizlet?

The solar constant is the amount of energy received at the top of the Earth’s atmosphere on a surface oriented perpendicular to the Sun’s rays (at the mean distance of the Earth from the Sun).

What is the meaning of the solar constant?

solar constant the total radiation energy received from the Sun per unit of time per unit of area on a theoretical surface perpendicular to the Sun’s rays and at Earth’s mean distance from the Sun. It is most accurately measured from satellites where atmospheric effects are absent.

What is the solar constant? Where is it measured? The solar constant is a measure of the rate of solar radiant energy received by the earth at the top of the atmosphere.. Make a sketch that shows what happens to the sun’s radiant energy as it passes through the earth’s atmosphere to the earth’s surface.

What is the solar constant measured at?

What is solar constant class 10th?

The solar constant is the measurement of the total radiation from the sun per unit of time per unit of area. The estimated value of the solar constant is around 1.36 kilowatts per square meter. Therefore its unit is Watt per square meter.

The value of the solar constant is 1.4kW/m².

What is solar constant Upsc?

Solar constant:

At the thermopause or 1000 km height from earth surfaces the amount of energy received per square meter of areas is called solar constant. It is generally 1366 Watt or 1.366 kilowatts per square meters areas per hour. … The solar constant is highest in the perihelion point of the orbit in January month.

What is intercepted solar radiation called?

Intercepted solar radiation is called. insolation. The uneven distribution of isolation by latitude is primarily a result of. Earth’s sphericity which presents varied angles to parallel solar rays.

What are the two main portions of the solar spectrum which enter the atmosphere?

Terms in this set (20) visible and infrared energy.

What is the solar radiation coming to Earth called?

What is the variation of solar constant with time and what is the reason for this variation?

What is the value of the solar constant in langleys?

LANGLEY single determination that the solar constant is 2.54 calories per square centimeter per minute.

What is called solar constant class 9?

The amount of energy that normally falls on a unit area of the Earth’s atmosphere per second when the Earth is at its mean distance from the Sun is called the Solar Constant.

How is solar radiation formed?

Solar radiation is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. The spectrum of solar radiation is close to that of a black body with a temperature of about 5800 K. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum.

What is spectral distribution of solar radiation?

What is tilt factor for beam radiation?

In case there is no possibility to move the surface at all the optimal tilt angle for the maximum amount of direct beam radiation is equal to the site’s latitude. … At 45° tilt angle the output is reduced to 85% of the maximum.

What is TSR Mcq?

terminate and stay resident program.

What are the two types of solar time Mcq?

Explanation: The two types of solar time are apparent solar time and mean solar time.

Which of the statement is correct about solar energy Mcq?

Which of the statements is correct about Solar Energy? Explanation: Solar energy is a source of energy that has not been used traditionally and is relatively new in terms of usage. Hence it is a non-conventional source of energy. It is unlimited and inexhaustible and hence is a renewable source of energy.

Who made the first solar cell Mcq?

Explanation: The first solar cell was made by Gerald Pearson in 1954 in Bell laboratories. It was a lithium-silicon photovoltaic cell. 10.

Is are constantly emitted by sun?

The Sun is the principal source of energy on the Earth’s surface. It is like a powerhouse which generates and gives out energy in the form of light and heat. This energy constantly emitted by the sun is known as solar energy.

Is solar radiation harmful?

Excessive exposure to the sun is known to be associated with increased risks of various skin cancers cataracts and other eye diseases as well as accelerated skin ageing. It may also adversely affect people’s ability to resist infectious diseases and compromise the effectiveness of vaccination programmes.

What is solar radiation answer?

Solar radiation often called the solar resource or just sunlight is a general term for the electromagnetic radiation emitted by the sun. Solar radiation can be captured and turned into useful forms of energy such as heat and electricity using a variety of technologies.

What is the reason for the energy surplus between the tropics?

In the tropics there is a net energy surplus because the amount of sunlight absorbed is larger than the amount of heat radiated. In the polar regions however there is an annual energy deficit because the amount of heat radiated to space is larger than the amount of absorbed sunlight.

What is true regarding dawn and twilight?

Dawn is the time that marks the beginning of twilight before sunrise. It is recognized by the appearance of indirect sunlight being scattered in Earth’s atmosphere when the centre of the Sun’s disc has reached 18° below the observer’s horizon.

What is the name of the location on Earth’s surface that receives the sun’s perpendicular rays?

What is the fate of solar radiation that reaches the Earth?

Solar energy that reaches the earth’s surface is re-radiated back to the atmosphere as heat also referred to as infrared radiation. Infrared radiation consists of much longer wavelengths. This re-radiated energy is likely to be absorbed by certain gases in the atmosphere such as carbon dioxide and nitrous oxide.

How does the sun keep Earth alive?

Without the Sun’s heat and light the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas stirs our atmosphere generates our weather patterns and gives energy to the growing green plants that provide the food and oxygen for life on Earth.

What are the four factors that affect the amount of solar energy Earth receives?

The amount and intensity of solar radiation that a location or body of water receives depends on a variety of factors. These factors include latitude season time of day cloud cover and altitude. Not all radiation emitted from the sun reaches Earth’s surface.

Why is the solar constant specified for Earth’s distance from the sun?

The solar constant is specified for earth’s distance from sun because solar power is constant for a given distance from the sun because there is no atmosphere to scatter and absorb the energy.
