The velocity of photon is proportional to (where v is frequency)

The wavelength of photon is proportional to (where upsilon = fequency)

In a phtoelectron effect energy of photon is directly proportional to the frequency and photons are totally absorbed by the electrons of metals then frequency and photons are totally absorbed by the electrons of metals then photoelectric current is:

The energy of photon is inversely proportional to its

Statement I : Photo-electric effect demonstrates particle nature of light. Statement II : Number of photons is proportional to frequency of photons.

A source of frequency n is moving with a uniform velocity v towards a stationary observer. If the velocity of sound is V, then the change in frequency would be -

The intensity of a wave is (a) Proportional to square of the frequency (b) Proportional to the velocity of wave (c) Proportional to the density of the medium (d) Proportional to the square of the distance of the source from the observer
