Answer 3
Answer 1 The angle formed at the point of incidence between the incident ray and the normal is called the angle of incidence. The angle formed between the refracted ray and the normal is called the angle of refraction.
Answer 2 A rainbow requires water droplets to be floating in the air. That's why we see them right after it rains. The Sun must be behind you and the clouds cleared away from the Sun for the rainbow to appear.
I hope it is helpful to you
