hich of the following is true regarding the properties of light?

Question

Question 9 options:

A)

Light has a dual nature and acts like both a wave and a particle.

B)

Light doesn't display interference or diffraction.

C)

Light can travel only in a straight line.

D)

Light needs a medium to propagate through a vacuum.

Answer 1

The correct answer is:

A) Light has a dual nature and acts like both a wave and a particle.

This statement is true according to quantum mechanics, which describes light as having both wave-like properties (such as interference and diffraction) and particle-like properties (as represented by photons). The other options are incorrect: light does display interference and diffraction (B), it can travel in various paths (not just straight lines) (C), and it does not need a medium to propagate; it can travel through the vacuum of space (D).
