Which wave characteristic is affected by the loudness or the intensity of sound?
Amplitude. (In the particle theory of light, brightness is determined by the number of photons).
A light waves brightness depends on the?
amplitude of the light wave!
What property of light is reflected by the amplitude of a light wave?
brightness
What does the amplitude of a light wave determine?
The amplitude of a light wave shows the light's brightness relative to waves of similar wavelength.
What is the physical dimension of light and sound that determines brightness and loudness?
Amplitude

What does the amplitude of a light wave determine?
The amplitude of a light wave shows the light's brightness relative to waves of similar wavelength.
What is the physical dimension of light and sound that determines brightness and loudness?
Amplitude
What features of light corresponds to loudness in sound?
The property is the amplitude, which corresponds to loudness for a sound wave or brightness for a light wave.
What property of a wave corresponds to the brightness of light or how loud a sound is?
the amplitude
What does the amplitude of a wave tell you?
Amount of energy in each wave. e.g. Loudness of sound, or Brightness of light Also the displacement of a wave.
What determines the color of a electromagnetic light wave?
Its wavelength/frequency.
What part of the transverse wave determines the color of light?
The wavelength
What does the brightness of light depend on?
The ultraviolet light contains photons of high energy. these are able to excite the atoms. which during the process of de-excitation can emit frequencies , which are detectable by normal eye. So it depends upon frequency of light..
What describes the amplitude of a wave?
The square of the amplitude gives the intensity of the wave. Intensity in case of sound is sensed as loudness and in case of light as brightness.
