Waves (2023-2024)

A disturbance that transfers energy from place to place

A wave that requires a medium through which to travel

A form of energy that can move through the vacuum of space.

A wave that moves the medium in a direction perpendicular to the direction in which the wave travels

matter in the medium moves back and forth along the same direction that the wave travels

the height of a wave's crest

Horizontal distance between the crests or between the troughs of two adjacent waves

the number of complete wavelengths that pass a point in a given time

frequency x wavelength

The bouncing back of a wave when it hits a surface through which it cannot pass.

The bending of a wave as it passes at an angle from one medium to another

The bending of a wave as it moves around an obstacle or passes through a narrow opening

the combination of two or more waves that results in a single wave

the time it takes one wavelength to pass a given point

Highest point of a wave

Lowest point of a wave

a part in a longitudinal wave where the particles are spread apart

The part of a longitudinal wave where the particles of the medium are close together.

a sound's intensity (amplitude)

a unit that compares the intensities of different sounds

a tone's experienced highness or lowness; depends on frequency

a reflected sound wave

A change in sound frequency caused by motion of the sound source, motion of the listener, or both.

a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously.

Electromagnetic waves with the shortest wavelengths and highest frequencies

Electromagnetic radiation having a very short wavelength; can penetrate substances such as skin and muscle.

part of the electromagnetic spectrum that consists of waves with frequencies higher than those of visible light and lower than those of x-rays

Electromagnetic radiation that can be seen with the unaided eye

Infrared light has longer wavelengths, penetrates more deeply, has less energy, and produces more heat than visible light; makes up 60 percent of natural sunlight.

Electromagnetic waves that have shorter wavelengths and higher frequencies than radio waves.

Electromagnetic waves with the longest wavelengths and lowest frequencies

the distance from the center of a lens to the focal point

A lens that is thicker in the middle than at the edges

A lens that is thinner in the center than at the edges

A colored chemical compound that absorbs light, producing color.

narrow beam of light traveling in a straight line

matter through which a wave travels

the angle of incidence is equal to the angle of reflection

the point at which rays parallel to the optical axis reflect and meet
