Answer 1

Hope this will help u

Answer 2

Light is made up of photons, which are energy packets that travel in a straight line at a high rate in a straight line.

Explanation:

• The property of light propagating in a straight line is known as rectilinear propagation.
• We can prove this by performing a simple activity of watching a burning candle through a curved hollow tube.
• We observe that we are not able to see the burning tube because the tube is curved and light always travels in a straight line, we cannot see a burning candle when looking through it. If the tube had been straight, the burning candle would have been visible.
