Sound and Light Megan Mayer

The highness and lowness of a tone.

A longitudinal wave that travels through a medium. Caused by vibrations.

A sound below the range of human hearing.

A sound with the frequency being above the human hearing range

It’s the unit for what relative intensity is messed in (dB)

The rate at which a sound wave moves energy through a medium

When two things are amplified and are vibrating at the same frequencies

When the wavelength is twice the length

When whole number multiples of that frequency

Determines distance by measuring time for the waves to reflect form a surface.

Inside of the cochlea that is a long and flexible membrane

A beam of light that has no mass like bundles of energy. A unit or quantum of light.

Depends on the amount of light. The number of photons that move through a given space.

Determines velocity and location of objects.

A full range of light that consists of all frequencies, energies, and wavelengths.

A line in space that matches the flow that light and energy travel.

An image that forms in a path of light rays that is not actually a path.

A line of light rays that actually come together to form a image.

When light rays go in random directions

When light behaves as a ray.

The angle of the light rays reflecting off the surface

The angle of the light rays striking the surface

The law in which the angle of reflection and the angle of incidence

A line perpendicular to the surface at the point where the light hits
