Chapter 12, Problem 2STP

To determine

To choose: The correct option.

Answer to Problem 2STP

Option A is correct.

Explanation of Solution

Introduction:

Light is a type of wave that carries energy through matter or space. Light waves carry radiant energy.

Opaque materials only absorb and also, reflect light; no light passes through them. Transparent materials transmit light without scattering it and because of this a person can see object clearly through it.

Incoherent light is bidirectional and also, it has more than one wavelength.

Coherent light is Uni-directional. It has similar wavelength and also, it emits waves that have same frequency. So, the correct option is (A).

Option B is incorrect because shown light wave is Uni-directional.

Option C is incorrect because shown light wave is Uni-directional.

Option D is incorrect because shown light wave is Uni-directional.

Conclusion:

Hence, the shown light wave is coherent light wave, the correct option is A.
