What is the spectrum contains photons of all energies

This is the electromagnetic spectrum.

answer: EMR

The ratio of output force to input force for a simple machine is called its advantage

The answer is mechanical advantage, not efficiency!

Sound waves are longitudinal mechanical compression waves

A. True

Electromagnetic waves differ only in their what their energy and their frequency

Wavelength.

How can you prove that light in the form of wave

in light photons are there they have energy and energy can be transfered in form of a wave so, it can be a wave
