The wavelength of blue light is greater than red light and its energy is greater.

The wavelength of blue light is greater than red light and its energy is greater. True or False

Answer

False The wavelength of blue light is smaller that than of red light.

And the energy of blue light is greater than that of red light. Energy of photons depend on its wavelength. Longer wavelength photons have less energy and shorter wavelength photons have more. Since the blue light photons have shorter wavelength than that of red light photons, blue light has higher energy than red light.
