A light wave can propagate

Options

Athrough a material medium
Bsolely through a material medium
Csolely through a vacuum
Dthrough a vacuum

Correct answer

D. through a vacuum

Step-by-step solution

Light is an electromagnetic wave. Electromagnetic waves do not require a material medium for their propagation, which means they can travel through a vacuum. They can also propagate through transparent material media such as glass, water, and air. Therefore, a light wave can propagate through both a material medium and a vacuum.
