Question

Orange light of 600 nm and violet of 360 nm are illuminating the thin film of index of refraction 1.2, which is surrounded by air. Next several questions will be about this particular film. 1. The minimum thickness of the film providing maximum reflection for both these wavelengths is equal to

Group of answer choices

three quarters of wavelength of orange light in the film

five quarters of wavelength of orange light in the film

three quarters of wavelength of orange light in the air

three quarters of wavelength of violet light in the film

one quarter of wavelength of orange light in the film

one half of wavelength of violet light in the film

exactly wavelength of orange light in the film

three quarters of wavelength of violet light in the film

one half of wavelength of orange light in the film

2. The next after minimum thickness of the film which provides maximum reflection for both wavelengths will be

Group of answer choices

2.5 times greater than in previous question

three times greater than in previous question

two times greater than in previous question

There will be no other thickness which provides maximum reflection for both wavelengths.

four times gretear than in previous question

3. The minimum thickness of a film which provides the total transmission for both wavelengths corresponds to

Group of answer choices

There is no thickness which satisfies this condition

3/2 of wavelength of violet light in the film

1/2 of wavelength of violet light in the air

5/2 of wavelength of violet light in the film

3/4 of wavelength of violet light in the film

1/2 of wavelength of violet light in the film

4. The next after minimum thickness which provides maximum transmission for both wavelengths is

Group of answer choices

2.5 times greater than in previous question

5/2 of wavelength of orange light in the film

5/4 of wavelength of violet light in the film

There is no another thickness to provide such conditions

4 times greater than in previous question

two times greater than in previous question

three times greater than in previous question
