Amplitude And Wavelength

A sine wave has an amplitude A and wavelength lambda . Let V be the wave velocity and v be the maximum velocity of a particle in the medium. Then

In Young's double slit experiment, the two slits acts as coherent sources of equal amplitude A and wavelength lambda . In another experiment with the same set up the two slits are of equal amplitude A and wavelength lambda but are incoherent. The ratio of the intensity of light at the mid-point of the screen in the first case to that in the second case is

In Young's double-slit experiment, the two slits act as coherent sources of equal amplitude A and of wavelength lamda . In another experiment with the same set-up the two slits are sources of equal amplitude A and wavelength lamda , but are incoherent. The ratio of the intensity of light at the midpoint of the screen in the first case to that in the second case is....

In a Young's double slit experiment, the two slits act as coherent sources of waves of equal amplitude A and wavelength lamda in another experiment with the same arrangement the two slits are made to act as incoherent sources of waves of same amplitude and wavelength. if the intensity at the middle point of the screen in te first case is I_(1) and in te second case I_(2) then the ratio (I_(1))/(I_(2)) is

Light from two coherent sources of the same amplitude A and wavelength lambda illuminates the screen. The intensity of the central maximum is I_(0) . If the sources were incoherent, the intensity at the same point will be
