1 state the laws of refraction and define refractive index 2 A beam of light is incident from air to water at an angle of 30°. Find the angle of refraction if the refractive index of water is 4/3​

d is the correct answer

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
