Definition | Term |
point of highest pressure in a longitudinal wave | |
a change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening | |
radio detection and ranging, a system that uses reflected radio waves to determine the velocity and location of objects | |
the distance from any point on a wave to an identical point on the next wave | |
an image that is formed by the intersection of light rays; this type of image can be projected on a screen | |
a line in space that matches the direction of the flow of radiant energy | |
slow vibrations of frequencies lower than 20 Hz | |
point of lowest pressure in a longitudinal wave | |
the increase of an object’s apparent size by using lenses or mirrors | |
the bending of a wave front as the wave front passes between two substances in which the speed of the wave differs | |
a pattern of vibration that simulates a wave that is standing still | |
a superposition of two or more waves that produces an intensity equal to the difference of the intensities of the individual waves, also known as cancellation | |
sound navigation and ranging, a system that uses acoustic signals and echoes to determine the location of objects or to communicate | |
in physics, the time that it takes a complete cycle or wave oscillation to occur | |
an image from which light rays appear to diverge, even though they are not focused there; cannot be projected on a screen | |
a measure of how high or low a sound is perceived to be, depending on the frequency of the sound wave | |
any sound wave with frequencies higher than 20,000 Hz | |
a superposition of two or more waves that produces an intensity equal to the sum of the intensities of the individual waves; also known as reinforcement | |
a unit or quantum of light | |
the lowest point of a transverse wave | |
