A similar question, Suppose we have a thin film of glass with an index of diffraction is n
The upper and lower surfaces of the flim is parellel. Light is incident to the flim.
So a portion of light is reflected at the upper surface, the rest is refracted into glass. Light continues to the...
note that equation 3.10: for diffraction grating, the condition for maxima in the interference pattern at the angle a is d.sina=m.lambda
(d = slit spacing. m=0,1,2... - order number, lambda=wavelength)
Suppose we have two source of disturbance to produce sound waves.
The intensity of sound produced by the first source at P is I1, and the other intensity is I2. So what is the intensity at point P.
I see many books saying that I=I1+I2. Can you explain why?

Hi everyone,
I have a question about waves.
Suppose there are two waves that make one water atom vibrate.
The first equation of oscillation is: x1= A1sin(wt+p1), energy propagated to the atom is (1/2)m.(w^2)(A1^2)
and the other: x2=A2sin(wt+p2), E2 = (1/2)m.(w^2)(A2^2)
so the total energy...
