Question

what would happen if the light does not traveling straight line​

Answer 1

Answer:

A: If light didn't travel in straight lines, it would be able to curve and travel around opaque objects; it would not be blocked, so a shadow would not form. Shadows prove light travels in straight lines.

Answer 2

Explanation:

Lightning basically tries to find the path of least resistance as it travels down to the ground. But this is not always a straight line because air is not a perfect mixture. There are fluctuations in temperature, humidity, pollutants, dust particles, etc. in the air, and so the resistance varies.
