Question:
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? \((\mu_{water}\)\(=\frac43)\)

- A thin transparent film with refractive index 1.4 is held on a circular ring of radius 1.8 cm. The fluid in the film evaporates such that transmission through the film at wavelength 560 nm goes to a minimum every 12 seconds. Assuming that the film is flat on its two sides, the rate of evaporation is:

- Assertion (A): When two waves of equal amplitude and a phase difference of \( \frac{\pi}{2} \) interfere, the resulting intensity is equal to the intensity of one wave. Reason (R): In interference, the resultant intensity is always the sum of individual intensities if the phase difference is non-zero.
