Question

Suppose a sound wave and a light wave have the same frequency.

Answer 1

Answer:

The light wave has a longer wavelength and has the greater speed.

Explanation:

light has a far more greater speed than sound. The speed of sound in air is about 343m/s while that of light is around  $3 *10^{8}m/s$

wavelength (λ) =$\frac{V}{f}$

since the frequencies of sound and light are same from the question, the wavelength would depend on the magnitude of their velocities. Light with a higher speed would have a longer wavelength.

Answer 2

Answer:

The light wave has a longer wavelength and has the greater speed.
