What is the definition of electromagnetic waves
a form of radiation travel through space and transfer energy.
what is the definition of trough
lowest point of a wave.
what is the definition of frequency
the number of occurrences of a repeating event per unit of time typically measured in hertz (Hz).
what is the definition of mechanical wave
distrurbances that transfer energy through a medium such as solids liquids or gases.
what is the definition of reflection
the phenomenon where a wave such as light sound or water bounces off a surface and returns to the original medium.
what is the definition of wavelength
the distance between two consecutive peaks or throughs of a wave.
a wave in which the particles of the medium move perpendicular to the direction the wave is traveling.
what is the definition of refraction
the bending of a wave such as light or sound as it passes from one medium into another with a different velocity.
what is the definiton of amplitude
the maximum distance moved by a point on a vibrating body or wave.
what is the definition of longitudinal wave
a wave vibrating in the direction of propagation.
what is the definition of diffraction
bending and spreading waves as they pass around an obstacle or through an opening.
what is the definition of convex
a shape that curves outward
what is the definition of crest
highest point of a wave
what is the definition of absorption
the process where a material takes in energy from a wave.
what is the definition of concave
a shape that curves inward.
