Just to be clear, the shorter the wavelength the higher the frequency and the longer the wavelength the lower the frequency?

Yes, that's correct. Frequency and wavelength have an inverse relationship, so frequency increases as wavelength decreases.

Correct. Frequency and wavelength are inversely proportional. As one increases, the other decreases.

Yes, short wavelength lights have high frequency and long wavelength lights have low frequency. This can be proved by using the electromagnetic equation c=vλ where c is the speed of light, v is the frequency, and λ is the wavelength. They have a universal relationship.

Yes, the shorter wavelengths have higher frequency and longer wavelengths have shorter frequency. This can be proven from the equation c=(lambda)(frequency) where c is a constant and equals 3.00x10^8 m/s. As wavelength increases, the frequency would have to decrease and vice versa in order to maintain the constant value of c. This shows that wavelength and frequency have an inverse relationship.

On a related note, is there any connection between the velocity of an electron and frequency? 1B.15 asks for wavelength of an ejected electron using a given velocity, so I am unsure of how to approach the problem.

Dr. Lavelle just clarified in lecture that this relationship only applies to electromagnetic radiation, so it can’t be used for all waves.
