Question

Which of the following describes the difference between red visible photons and blue visible photons?



A Blue photons carry more energy and move faster than red photons

B. Blue photons carry less energy and move slower than red photons

C. Blue photons carry more energy and move at the same speed as red photons o Blue photons carry less energy and move at the same speed as red photons

Answer 1

Blue photons are of shorter wavelength and higher frequency than red photons, and therefore carry more energy than red photons. But all photons move at the same speed in a vacuum. The only correct statement among the given choices is

Blue photons carry more energy and move at the same speed as red photons.
