Electromagnetic Radiation and Speed

Postby Bianca Barcelo 4I » Fri Dec 07, 2018 11:36 pm

Why is that higher wavelengths travel faster in comparison to smaller wavelengths?

If we talking about DeBroigles wavelength, it is because velocity and wavelength are inversely proportionate. A bigger wavelength means smaller speed while a smaller wavelength means bigger speed. If we are talking about the wavelength in reference to light, the speed is always the same since it is the speed of light.

In terms of De Brogile's equation, wavelength and velocity are inversely proportional. Other than that, speed of all waves should be the same (3x10^8ms-1).
