What happens to an electromagnetic wave when if hits a transparent obstacle?
The wave will pass through the transperent object
What happens when sound hits a surface?
It bounces back.
What happens when a waves energy is lost to a surface making the wave weaker?
Absorption. -Apex
What happens when a sound wave hits a small thin membrane?
The membrane (such as you eardrum) vibrates.
What is a small wave called?
surface wave
Distinguish between a primary wave and a secondary wave?
A primary wave is a strong vibration or wave that hits earths surface (P) and a secondary wave (S) is a wave that hits soon after but not nearly as big.
When a wave hits a surface and bounces back it undergoes?
reflection
What happens to an electromagnetic wave when if hits a transparent obstacle?
The wave will pass through the transperent object
What happens to a duck on the surface of a pond when a wave passes under it?
it sinks
What is the difference between primary and secondary waves?

What happens when light hits a rough surface?
when light hits a rough surface it scattters.
What happens to the angle of the wave if it hits the perspex at 90 degrees?
It does not change.
What happens to the sunlight that hits the surface of the Earth?
Sunlight that hits the Earth's surface is absorbed by the Earth. It is then reflected back.
What happens when sound hits a surface?
It bounces back.
What happens when a wave hits a barrier it cannot pass through?
A mechanical wave travels through a medium because a medium is necessary for the propagation of that wave. With a mechanical wave, like sound, mechanical energy is put intothe wave, and the medium carries the energy of the wave. This is in contrast to an electromagnetic wave (like light) which can move through a total vacuum.
When a wave hits a surface through which it cannot pass it bounces back and undergoes what?
Reflection
What happens to the amplitude of a wave as strong winds blow it over the ocean's surface?
The amplitude is increased by strong surface winds.
