Answer 1

The wavelength and frequency of light are smaller inside a raindrop compared to in air, and the speed of light is also slower inside a raindrop.

Step-by-step explanation:

In a raindrop, the wavelength of the light is less than the wavelength of the same light in air. This is because the light waves slow down and bend when they enter the raindrop, causing a decrease in wavelength.

Similarly, the frequency of the light inside a raindrop is less than the frequency of the same light in air. This is because the frequency is inversely proportional to the wavelength. So, a shorter wavelength inside the raindrop corresponds to a lower frequency.

The speed of light inside a raindrop is less than the speed of light in air. The speed of light depends on the medium it is passing through, and since the raindrop is denser than air, it slows down the light.
