Question

the colour of light is determined by its
a)velocity
b)frequency
c)amplitude
d)intensity

Answer 1

Answer:

The colour of light is determined by its

c) amplitude

Answer 2

Option c amplitude is the right answer.

• The color of light is determined by its wavelength.
• Wavelength is the distance between two compressions and rarefactions.
• The longest wavelength of the spectrum is associated with red light and the shortest wavelength is associated with violet wavelength.
• Amplitude is the maximum displacement from the mean position on vibration.
• It gives information about the intensity of the light.
