Answer:
Current (I) = 3 x 10^-2 A
Explanation:
As we know,
By putting up the values needed from the data...
Current (I) = 2 x 3.14 x (3.0 x 10^-6) (2.0 x 10^-3) / 4 x 3.14 x 10^-7 = 3 x 10^-2 A
Coherent light with wavelength 490 nm passes through two very narrow slits that are separated by 0.200 mm, and the interference
1 answer:
Double slit diffraction has a convenient formula for this of
Where s is the distance between the fringes, w is the wavelength (should be lambda but this website doesnt seem to like it in the formula construction box), D is the distance slit to screen, and d is the distance between the centres of the two slits.
Substituting this all in:
