Tools we'll need:
Speed of EM wave in vacuum = 3 x 10⁸ meters per second.
Frequency = (speed) / (wavelength)
Period = 1/frequency

Period = (wavelength) / (speed) = (0.15) / (3 x 10⁸) = <u>0.5 nanosecond</u>

( "nano..." = 10⁻⁹ )

Tatiana [17]

Answer:

D). A sudden change in temperature increased the density of the atmosphere.

Explanation:

The claim that can be made and supported with evidence regarding the temporary decrease in light would be 'a sudden change in temperature will increase the density of the atmosphere.' <u>As the temperature increases, the molecules in the atmosphere begin to move fastly which causes a decrease in atmosphere density while it increases with the fall in temperature. As a result, the intensity of sunlight gets affected due to molecules being heavier and floating in the atmosphere</u>. Thus, <u>option D</u> is the correct answer.
