Answers
Answer:
The Sun appears about two minutes before the actual sunrise and this phenomenon is known as advance sunrise. The Sun remains visible about two minutes after the actual sunset and this phenomenon is known as delayed sunset. The advance sunrise and delayed sunset happen due to atmospheric refraction.
Answer:
What is refraction of light? Simply put, a ray of light ‘bends’ when it travels from one medium to another. This ‘bending of light’ is called refraction of light. If the light ray travels from a rare medium to a denser medium, it bends towards the imaginary normal and if it travels from a dense medium to a rarer medium, it bends away from the imaginary normal. Depending on the density of the different medium, the speed of the travelling light ray keeps varying, and this causes it to slow down or speed up, therefore bending in the process.
