The intensity ratio of the two interfering beams of light is m. What is the value of `I_("max")-I_("min") // I_("max")+I_("min")`?

Two coherent sources of intensity ratio beta^2 interfere. Then, the value of (I_(max)- I_(min))//(I_(max)+I_(min)) is

Two coherent sources of intensity ratio alpha interface . In interference pattern (I_("max") - I_("min"))/(I_("max") + I_("min")) =

Two coherent sources of light of intensity ratio beta produce interference pattern. Prove that in the interferencepattern (I_(max) - I_(min))/(I_(max) + (I_(min))) = (2 sqrt beta)/(1 + beta) where I_(max) and I_(min) are maximum and mininum intensities in the resultant wave.

Let I_1 and I_2 be intensities of two sources such that (I_1)/(I_2) = k . Find value of (I_("max") - I_("min"))/(I_("max") + I_("min")) .

The interference pattern is obtained with two coherent light sources of intensity ratio n. In the interference patten, the ratio (I_(max)-I_(min))/(I_(max)+I_(min)) will be

Two coherent sources of light of intensity ratio beta interfere. Prove that the interference pattern, (I_(max)-I_(min))/(I_(max)+I_(min))=(2sqrtbeta)/(1+beta) .
