What happens when electromagnetic waves encounter matter?
The waves are passed thru the matter or reflected by the matter or absorbed by the matter.
What happens when EM waves encounter a material medium?
The energy in the wave is partly transmitted, partly absorbed, and partly reflected.
The spreading of waves into the region behind an obstacle is known as?
Diffraction.
What are the Types of waves encounter daily?
Water waves, sound, light.
What is meant by diffraction?
Diffraction is bending of waves from the corners of opaque obstacle and it's enchroachment within the geometrical shadow of opaque obstacle.
What happens when transverse electromagnetic waves encounter cavity?
light waves or electromagnetic waves are transverse and sound waves are longitudinal
What happens when electromagnetic waves encounter matter?
The waves are passed thru the matter or reflected by the matter or absorbed by the matter.
Explain what happens when waves encounter a medium that they cannot travel through?
They reflect back.
What are four different things that can happen to the waves when they meet an obstacle?
In general waves can: Wrap around the obstacle. This happens when the wavelength is larger than obstacle size. Bounce back as an echo off the obstacle. This happens when the wavelength is shorter than the obstacle size. Be absorbed by the obstacle. This occurs when the natural frequency of the obstacle matches the frequency of the wave...so-called resonance. Pass through the obstacle. There are several ways this can happen. But visible light passing through a glass window is one example.
