In the two-slit experiment, monochromatic light of frequency 5.00 × 1014 hz passes through a pair of slits separated by 2.20 × 10-5 m. (c = 3.00 × 108 m/s) (a) at what angle away from the central bright spot does the third bright fringe past the central bright spot occur?

Explanation:

It is given that,

The frequency of monochromatic light,

Slit separation,

Let is the angle away from the central bright spot the third bright fringe past the central bright spot occur. The condition for bright fringe is :

n = 3

So, at 4.64 degrees the third bright fringe past the central bright spot occur. Hence, this is the required solution.

you would expect a sound wave to speed up. - b)

like poles repel so keep pushing north to north and repels funny to see this
