A wave front is a line or surface on which the disturbance has the similar phase at every position. If the source is periodic, it generates a succession of ray front, each of the same shape. Ripples on a pond are the example of wave fronts.
What is Attenuation? Attenuation: Attenuation is a reduction within the amplitude and intensity of a signal. This is a significant property into optical communications. This
In the device shown in Figure, when the current in the primary coil of 1000 turns increases linearly from 1A to 6A in 200ms, an e.m.f. of 15V is induced into the secondary coil of
The rate of change of angular velocity with related to time is known as angular acceleration.
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
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.
Rotating a Mirror and the Reflected Ray Describing in which when a mirror is rotated through an angle, the reflected ray is rotated through twice that angle. You might drag th
2-Point Source Interference Changing Wavelength The intrusion of two sets of circular waves along with the similar frequency and the similar amplitude results within a standing
* Question 1 : Sound A has intensity 10 times the threshold if hearing : sound B has intensity 100 times the threshold of haring . How much louder do we perceive sound B ? * Ques
