9.Which of the following is false?

a. Radiation travels at the speed of light.

b. Radiation may be classified according to wavelength.

c. Radiation from the sun is absorbed by Earth is re-radiated as shorter wavelength radiation.

d. Radiation refers to a process of energy transfer.

Your answer:  c

Explanation / Answer

Ans- 1: b

The shortest day of the year and known as winter solstice, the vertical rays of sun strikes tripic of capricon.

Ans- 2- C radiation depends on intensity and duration that's why amount of radiation keeps on decreasing from equator to poles.

Ans- 3-C

Conduction results in transferring of heat energy from one particle to next due to variation in temperature.

4. b

Altitude

5. a

Radiation as convection and conduction requires medium for energy transfer.

6. b

The distance from sun has almost no effect on seasoand it can be exemplified by the occurrence of winter solstice in northern hemisphere while it is neatest to the sun.

7.b

June 21 is the day of summer solstice in northern hemisphere causing long days.

8. C

Short wave

Since sun radiation consists of very high energy to pass on it is short wave.

8. C

analemma

9. C

In fact the earth emits radiation in the form of long wave radiation.
