In a vacuum photons of lower energy
WebApr 19, 2016 · 1. Photons can produce shock waves in water or air, similar to sonic booms. Nothing can travel faster than the speed of light in a vacuum. However, light slows down in air, water, glass and other materials as photons interact with atoms, which has some interesting consequences. The highest-energy gamma rays from space hit Earth’s … WebMultiple choice: In a vacuum, photons of higher energy (a) move faster than lower-energy photons; (b) have higher frequencies and shorter wavelengths than lower-energy …
