For each of the following, describe the relationship as directly or inversely proportional:

a) wavelength vs. frequency

b) wavelength vs. energy

c) frequency vs. energy ... ?

The relationships can best be described as follows:

As frequency increases, wavelength decreases. The greater the energy, the larger the frequency and the shorter (smaller) the wavelength.

a) wavelength vs. frequency = inversely proportional

b) wavelength vs. energy = inversely proportional

c) frequency vs. energy = directly proportional

Hope this answers the questions. Have a nice day. Feel free to ask more questions.
