## How does the electromagnetic spectrum work?

speed of light V= e frequency wavelength E=hv (Planck's constant) x (frequency)

Planck's constant a= my wavelength = mass) (frequency) (de Broglie]

L Kwavelengthy

-node Amplitude The Electromagnetic Spectrum low frequency

## What is the schrodinger wave equation for hydrogen atom?

-> high frequency low energy

-> high energy longer wavelength > Shorter wavelength
