The difference between sunlight and moonlight.
Answer to Problem 1Q
Sunlight comes from the large star called the Sun and falls on the earth directly. The Moonlight is the sunlight which is reflected from the Moon to the Earth.
Explanation of Solution
Introduction:
Sun is the only star in the solar system. Life is possible on earth due to the presence of Sun. All the planets, moons and other smaller objects in the solar system revolve about the sun in elliptical orbits with sun at one of the foci of the elliptical path. Moon is the natural satellite of the Earth. It appears bright in the night sky and has different phases.
Sunlight that is emitted by the Sun is a form of
However, moonlight is the reflection of the rays of the sun that get reflected when falling on the moon.
Sunlight is not affected by any celestial body, whereas moonlight is another form of sunlight that is affected by a celestial body.
An example: Take a flashlight and a mirror; shine the flashlight into the mirror at any angle and also to the wall. The light from the flashlight that hits the wall is like moonlight, whereas the light that emerges from the flashlight directly striking the surface of the wall is like sunlight.
