Sound and light Chelsea

Sounds that are to soft for the human ear to hear

A longitudinal wave caused by vibrating objects and it has to travel through a medium.

Noise frequency that is above human hearing

When two objects vibrate at the same frequency

The rate at which the sound waves travel through a medium

The unit that intensity is measured in

The frequency of a standing waves vibration

The vibration of the fundamental frequency and a certain whole number and multiplied.

System that uses signals and echo returns to determine the location of the object.

A long flexible membrane in the cochlea. Different parts of it vibrate at different frequencies.

A unit or quantum of light. Ex. Light beam is a stream of photons because they don’t have mass.

Use radio waves to determine the velocity and location of an object.

Light at all possible energies, frequencies, and wave lengths.

An imaginary line that is running in the direction that light travels.

Image that forms at a location where the light rays appear but they are not actually there

Image of the object that is formed by the light rays where they actually come together.

When the reflection of light is reflected in all different directions.

When you are studying light in cases where it is a ray.

Mirrors that bulge out and makes the light rays go in different directions.

A mirror that is indented. It takes the light rays and moves reflects them towards one another.

Reflection that takes place in a substance when the light rays that are reflected are the same as the real ones but the real light is less than the critical angle.

Transparent object that reflects lights to come together or move away to create an image.

The change is the same of the object compared to its actual size.

A system that has two or more transparent smooth surfaces that are at an angle from each other.
