NEET 2019, Physics Q6: Young’s Double Slit Experiment
NEET2019Paper 2019Physics
Q.
In a double slit experiment, when light of wavelength 400 nm was used, the angular width of the first minima formed on a screen placed 1 m away, was found to be 0.2°. What will be the angular width of the first minima, if the entire experimental apparatus is immersed in water? (water = 4/3)
- A
0.266°
- B
0.15°
- C
0.05°
- D
0.1°
