Which has the higher frequency red light or blue light

Asked by admin @ in Geography viewed by 363 People

Compared to red light, blue light has higher frequency and (a) higher energy and shorter wavelength. (b) higher energy and longer wavelength. (c) lower energy and shorter wavelength.

Answered by admin @


Answer: (a) higher energy and shorter wavelength.

Explanation: The energy of light wave is proportional to its frequency. Thus high frequency light has high energy and short waves while low frequency light has low energy.

Shorter waves vibrates at higher frequencies and have higher energies. Blue light has a shorter wavelength than the red light, which implies it has a greater frequency compared to the blue light.
