Physical Science - Waves
The distance between two consecutive similar points on a wave, such as two crests or troughs.
"Different colors of light have different wavelengths."
The number of waves that pass a fixed point in a given unit of time, typically expressed in hertz (Hz).
"A higher frequency results in a higher pitch sound."
The bouncing back of a wave when it hits a surface it cannot pass through.
"The reflection of sound waves can create echoes."
The bending of waves as they enter a new medium at an angle.
"A straw looks bent in water due to the refraction of light."
The spreading out of waves as they pass through an opening or around the edges of an obstacle.
"Diffraction is why you can hear sounds around corners."
The interaction between waves that meet, which can result in a new wave pattern.
"Interference can be constructive or destructive, affecting the resulting wave's amplitude."
