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.

1. The minimum thickness of the film providing maximum reflection for both these wavelengths is equal to  Choices-(*exactly wavelength of orange light in the film; *three quarters of wavelength of orange light in the film; *five quarters of wavelength of orange light in the film; *one half of wavelength of violet light in the film; *one half 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; *three quarters of wavelength of violet light in the film)

2. The next after minimum thickness of the film which provides maximum reflection for both wavelengths will be
Choices-(*two times greater than in previous question; *four times gretear than in previous question; *three times greater than in previous question; *2.5 times greater than in previous question; *There will be no other thickness which provides maximum reflection for both wavelenths.)

3. The minimum thickness of a film which provides the total transmission for both wavelengths corresponds to
Choices-(*1/2 ofwavelength of violet light in the air; *5/4 ofwavelength of violet light in the film; *3/4 ofwavelength of violet light in the film; *3/2 ofwavelength of violet light in the film; *There is no thickness which satisfies this condition; *5/2 ofwavelength of violet light in the film; *5/2 ofwavelength of orange light in the film; *1/2 ofwavelength of violet light in the film)

4. The next after minimum thickness which provides maximum transmission for both wavelengths is Choices-(*There is no another thickness to provide such conditions; *2.5 times greater than in previous question; *three times greater than in previous question; *two times greater than in previous question; *4 times greater than in previous question)
