the frequency of a wave does not change as it passes from one medium to another. what will most likely happen if a light wave moves from the air into a solid? o the wavelength of the light wave will increase. o the speed of the light wave will decrease. o the wavelength of the light wave will remain the same. o the speed of the light wave will remain the same.
Answer
Brief Explanations:
When a light - wave moves from air into a solid, the refractive index of the solid is generally higher than that of air. The relationship between the speed of light ($v$), frequency ($f$), and wavelength ($\lambda$) is $v = f\lambda$. Since the frequency $f$ remains constant and the refractive index $n=\frac{c}{v}$ (where $c$ is the speed of light in vacuum) increases in the solid, the speed $v$ of the light - wave decreases.
Answer:
The speed of the light wave will decrease.
