Answer:
The distance of the second dark band away from the central bright spot be located is 
Explanation:
Given that,
Wave length = 500 nm
Radius 
Distance from the hair sample D= 6 m
We need to calculate the distance of the second dark band away from the central bright spot be located


Using formula for dark fringe

Put the value into the formula




Hence, The distance of the second dark band away from the central bright spot be located is 
Answer: Option 5.
Decreases increases increases.
Explanation:
Electromagnetic spectrum refers to differences in frequencies, wavelengths and photon energies of electromagnetic radiation.
From the top of the list to the bottom i.e from radio waves, infrared waves, visible lights, ultraviolet radiation, gamma radiation, wavelengths decreases, the frequency increases as the photon energy increases.
The electromagnetic radiations : radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays have high-frequency and short wavelengths. Their wavelengths decrease. The photon energy is directly proportional to wave frequency.
