What are some wave facts about science

waves are emitted by all objects but not visible to humans

the hotter the object, the more it emits

wave speed=frequency x wavelength

the higher the frequency, the shorter the wavelength.

the larger the amplitude, the greater the energy of the wave.

diffraction is when waves pass through a gap and spread out.

the longer the wavelength, the greater the diffraction.

electromagnetic waves transfer energy. examples are :gamma, x-ray, UV, visible light, infrared radiation, microwave and radio.

got these facts out of my physics book, hope they help :)

e/c, where e is its total energy

because if the tool that you are using is not balanced it there would be false mass.
