Questions and Answers

What is the difference between transverse and longitudinal waves?

Transverse waves are waves in which the particles of the medium vibrate parallel to the direction of wave travel, while longitudinal waves are waves in which the particles vibrate perpendicular to the direction of wave travel.
Transverse waves are always visible to the human eye, while longitudinal waves are not visible.
Transverse waves are waves in which the particles of the medium vibrate perpendicular to the direction of wave travel, while longitudinal waves are waves in which the particles vibrate parallel to the direction of wave travel. (correct)
Transverse waves are only found in two-dimensional mediums, while longitudinal waves are found in three-dimensional mediums.

What is the Superposition principle in relation to waves?

The Superposition principle is only applicable to transverse waves.
The Superposition principle states that when two or more waves meet at a point, the resulting displacement is the algebraic sum of the displacements of the individual waves. (correct)
The Superposition principle explains the refraction of light in different mediums.
The Superposition principle states that only one wave can exist at a given point in a medium at any time.

What is the Huygens-Fresnel principle related to?

The Huygens-Fresnel principle explains that each point on a wavefront serves as a source of spherical wavelets that spread out in the forward direction at the speed of light. (correct)
The Huygens-Fresnel principle describes the behavior of sound waves when reflected off surfaces.
The Huygens-Fresnel principle is only applicable to one-dimensional harmonic waves.
The Huygens-Fresnel principle explains the Doppler frequency shifts in sound waves.
