Answer:
Plutonium, has formula Pu with molecular mass 94
Explanation:
Answer:
t = 200 nm
Explanation:
It is given that,
Wavelength of a light beam is 500 nm
It is reflected constructively from a thin layer of oil having index of refraction 1.25.
The oil floats on the top of water of index of refraction 1.33.
We need to find the minimum thickness of the layer of oil. `
For constructive interference,
m is 1 for minimum thickness
n is refractive index of oil
t is thickness of layer of oil.
So,
So, the minimum thickness of the layer of oil is 200 nm.
