Question

How does an increase in
amplitude affect sound and
light waves? (1 point)
louder sound and
brighter light
higher-pitched sound
and longer
wavelengths for light
higher-pitched sound
and brighter light
louder sound and
longer wavelengths for
light

Answer 1

An increase in amplitude affects sound and light waves by making the sound louder and the light brighter. Therefore, the correct answer is:
