Several of them.

Wavelength = speed of light/Hertz

Wavelength = Planck's constant/mass of particle*Hertz

And a few more that can be manipulated to find wavelength that I will let you discover on your own.

### Which wave would have more energy a small wave or a large wave?

I suppose you're talking about small wavelenght or large wavelength. In this case, the answer is that a wave with lower wavelenght has more energy than a wave with higher wavelenght.You have to consider that the energy associated to an electromagnetic wave is, according to de Broglie:E = hfwhere h is the Planck constant (which is, more or less, h = 6.626&Acirc;&middot;10-34 Js) and f is the frequency of the wave. The relationship between frequency and wavelenght is given byf = c/lambdawhere c is the speed of light and lambda the wavelenght. So finally you haveE = hc/lambdaAccording to this equation, the higher the wavelenght, the lower the energy.

### What does increasing the wavelength of an electromagnetic wave decrease?

Increasing the wavelength of an electromagnetic wave decreases its frequency. This is because wavelength and frequency are inversely related in electromagnetic waves, as described by the equation λν = c, where λ is wavelength, ν is frequency, and c is the speed of light.
