Both sound and light waves reflect. Sound waves reflect off of objects to create an echo. Light waves reflect off of objects and point the light in another direction.
Loudness is to brightness as sound is to light.
Loudness or volume
Intensity (brightness) and energy (frequency).
brightness and size - yousaf
yes. it is volume or loudness.
The amplitude of a light wave shows the light's brightness relative to waves of similar wavelength.

Light exhibits wave and particle properties.
Brightness refers to amount of light, 100% is maximum light and 0% is minimum light or no light - black.
Light has both wave and particle properties. In some cases, the wave property is observable (Young's double slit experiment) and in other cases, the particle property is observable (photoelectric effect).

Then the brightness of the light buld increases.
transverse; longitudinal.
A pencil has nothing to do with the brightness of a light bulb.
