Study quantum mechanical scattering, t and r coefficients in 1-d

Which object is most likely represented by a dot?

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?

While standing outdoors one evening, you are exposed to the following four types of electromagnetic radiation: yellow light from a sodium street lamp, radio waves from an am radio station, radio waves from an fm radio station, and microwaves from an antenna of a communications system. rank these type of waves in terms of increasing photon energy.
