Relation between phase difference and path difference is path difference/wavelength=phase difference/2*pi
Compression waves (as opposed to transverse waves).
Refracted Wavefront is the bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves.
plane waves , spherical waves , cylinderical waves
Mechanical waves require a medium to travel, where electromagnetic waves do not.
Because the path difference or the phase difference between two waves is zero
difference between shortest path and alternate path
Relation between phase difference and path difference is path difference/wavelength=phase difference/2*pi
The waves will be bent or reflected.
Compression waves (as opposed to transverse waves).
1 micrometer (1,000 nm)
Compression waves (as opposed to transverse waves).
P waves move along a horizontals path, expanding and contracting material.
Surface waves cause rock to move in a circular path.
to detect ultrasonic waves ,place a sensitive flame in its path. if it flickers it proves its existence.
Refracted Wavefront is the bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves.
The path difference is the difference in the physical distance between the two sources to the observer, i.e., the difference in distance travelled from the source to the observer.
