Question

Which of the following is not a property of light(a) It requires a material medium for propagation(b) It can travel through vacuum(c) It involves transportation of energy(d) It has finite speed

Answer 1

" A) it requires a material medium for propagation " is false because light can pass through vaccum

Answer 2

The statement stating, "It requires a material medium to travel", is false.

• Light is an electromagnetic wave i.e, it is the propagation of electromagnetic oscillations which doesn't require a material medium to propagate. So this statement is false.
• Since it doesn't require any material medium, light can travel through a vacuum too. So, this statement is true.
• We know that electromagnetic radiations carry energy and momentum. So light transports energy. This statement is true.
• Light travels in with its maximum speed $c=3*10^8m/s$ in a vacuum. This is a finite value. Hence, this statement is true.
