Diffraction is observable when the is smaller than the wavelength 
harkovskaia [24]3 years ago

Answer:

The opening needs to be smaller

Explanation:

Diffraction can be observed when the light passes through a grid or an opening that has a width of about the same size or smaller than the wavelength of the light that is being used.

We need the opening to be smaller than the wavelength so the bean can be splitted and we are able to see diffraction.

One of the checks that you could do for problem 1) would be to check the output resistance of the Wheatstone bridge to make sure
Ray Of Light [21]

Answer:

Explanation:

Let the four resistances of th wheat stone bridge is

P, Q, R and S and the value of each is 350 ohm.

Here, P and Q are in series.

R' = P + Q = 350 + 350 = 700 ohm

Then R and S are in series

R' = R + S = 350 + 350 = 700 ohm

Now R' and R'' are in parallel.

So, the equivalent resistance is

Req = R' x R'' / ( R' + R'')

Req = 700 / 2 = 350 ohm

Thus, the reading of ohmmeter is 350 ohm.
