Doctors can use X rays to diagnose broken bones because bones absorb X rays. The transfer of energy by electromagnetic waves is called radiation . Diffraction grating is a device that has many rows of equally spaced grooves that also produce interference patterns. Transverse waves are any wave in which the motion of the wave disturbance is at right angles to the direction the wave travels. Longitudinal waves are any wave in which the motion of the wave disturbance is the same direction as the wave.
Constructive interference is when the crest of one wave aligns with the trough of another wave.
The number of waves per second is the frequency . X rays, radio waves, ultraviolet waves, infrared radiation, microwaves. People with swimming pools often cover them to use the sun to help heat the water. Name a type of electromagnetic energy that your body gives off. Complete the chart below.
