Answer

Answer:

B. The speed of the light wave will decrease.

Explanation:

Step1: Recall wave - speed formula

The speed of a wave is given by $v = f\lambda$, where $v$ is speed, $f$ is frequency and $\lambda$ is wavelength.

Step2: Consider frequency constancy

The frequency $f$ of a light - wave is constant when it passes from one medium to another.

Step3: Analyze medium change

When light moves from air (less dense) to a solid (more dense), the speed of light decreases. Since $v = f\lambda$ and $f$ is constant, when $v$ decreases, $\lambda$ also decreases. So the speed of the light wave will decrease as it moves from air into a solid.
