What happens when two waves interfere?
Interference is the process of superposition of two waves having the same wavelength, amplitude, and frequency. When the waves interfere, there is no loss of energy. During constructive interference, the two waves are added up to give a resultant wave…

Difference between plane wave and spherical wave
The basic difference between plane wave and spherical wave is that in plane wave disturbances propagated in single direction like string wave, while in spherical waves disturbances propagated outward in all directions from the source of wave.Light waves is an…

Why resistivity of semiconductors decreases with temperature?
Solid materials having properties in between conductors and insulators are known as semiconductors. A semiconductor is a material that is neither a good conductor nor a good insulator of electricity. Its resistivity lies in between conductors and insulators, which is…

Does a photon have a de Broglie wavelength?
Yes a photon has de Broglie wavelength.In 1924,Louis de Broglie proposed that a particle must also act like wave,in silmilar way,wave behave like particles. In de Broglie hypothesis an electromagnetic wave is the de-Broglie wave for a photon moving with…
