Question
1. constructively
2. is no
3. is a
4. a phase shift of 12
5. no phase shift
6. destructively
7. a phase shift of
When illuminated from above at A, light ray reflected from the air-oil interface undergoes___________.
A light ray reflected from the oil-water interface undergoes____________.
If the oil thickness at A is negligible compared to the wavelength of the light, then there____________significant shift in phase due to a path distance traveled by a ray in the oil
Thus the light reflected from the two surfaces will____________interfere for all visible wavelengths, and the oil will appear black when viewed from above.
Explanation / Answer
I have very clear his writing, but I'll try to respond to the initial faces
Frase 1)
When illuminated from above at A, light ray reflected from the air-oil interface undergoes______
no phase shift
Explanation: When moving from a higher refractive index material of another material with menor index the phase of the wave changes np / 2, but if the reflection is in the same medium no phase change
Frase 2
A light ray reflected from the oil-water interface undergoes____________.
a phase shift of /2
The oil has a greater refractive index than air
Frase 3
If the oil thickness at A is negligible compared to the wavelength of the light, then there____________significant shift in phase due to a path distance traveled by a ray in the oil
is a
Frase 4
Thus the light reflected from the two surfaces will____________interfere for all visible wavelengths, and the oil will appear black when viewed from above.
Destuctuctively
the beam reflected from the surface and the inside of the oil droplet has a phase shift of / 2 which interfere destructively
