Waves and Optics Flashcards
1
Q
What is a transverse wave?
A
A type of wave that is perpendicular to the direction of the energy transfer
2
Q
What is a longitudinal wave?
A
A type of wave that is parallel to the direction of the energy transfer
3
Q
Amplitude
A
the maximum displacement of a particle from its equilibrium position. The intensity of a wave depends on amplitude
4
Q
Frequency
A
the number of cycles or vibrations of a particle per second or the number of complete waves passing a point per second
5
Q
Photoelectric effect
A
When electrons are emitted from the surface of a metal when electromagnetic radiation above a specific frequency is directed at a metal
