### Equations

Which equations apply to electromagnetic radiation and which ones would not work?

### Re: Equations

I believe the only one that doesn't apply to EM radiation is the De Broglie equation. The others deal with light therefore they are EM radiation equations.

### Re: Equations

I think it is also important to mention that a lot of the equation we have discussed in this unit concern many of the same variables such as wavelength and frequency and you can use multiple equations or a combination of them to find the value you need.

### Re: Equations

De Broglie does not apply to electromagnetic radiation as it is focused on objects with mass and momentum. All others (that we have learned at least) are EM equations

### Re: Equations

Most of the equations we've learned to apply to EMR, but as others have said, not the De Broglie Equation. Something that may help you remember this is that most of the equations we've learned have similar or related variables and the De Broglie equation involves mass and velocity (momentum) so they deal with to separate things.
