Q Define threshold frequency?
The minimum frequency of incident radiation lower which the photoelectric emission isn't possible completely but high the intensity of incident radiation may be. The threshold frequency is dissimilar for different metals.
An electron has momentum that is 90 % larger than its classical momentum. Find speed of electron. Classical momentum Relativistic momentum Here m is effective mass Given, Spe
A car is moving along a straight horizontal road at a speed of 20 meters per second. The brakes are applied and a constant force of 5000 Newtons decelerates the car to a stop
if in an interference pattern,the ratio between maximum and minimum intensities is 36:1,find the ratio between the amplitude and intensities of the two interfering waves.
Two waves of equal frequency have amplitudes 2 units and 3 units respectively. When they superpose coherently the intensity of the resultant wave is I 1 . The intens
