Question

A) How does an increase in amplitude affect sound and light waves? (1 point)
higher-pitched sound and longer wavelengths for light
louder sound and brighter light
higher-pitched sound and brighter light
louder sound and longer wavelengths for light
A) What happens to the wavelength when the frequency increases? (1 point)
The wavelength stays the same
The wavelength increases if the speed increases
The wavelength decreases.
The wavelength increases

Answer 1

A) An increase in amplitude affects sound and light waves by making the sound louder and the light brighter. So the correct answer is: **louder sound and brighter light.**

B) When the frequency increases, the wavelength decreases. So the correct answer is: **The wavelength decreases.**
