In a Young's double slit experiment, the slit separation is $1 \mathrm{mm}$ and the screen is $1 \mathrm{m}$ from the slit. For a monochromatic light of wavelength $500 \mathrm{nm}$, the distance of $3\mathrm{rd}$ minima from the central maxima is

In Young's double slit experiment using monochromatic light of wavelength $\lambda$, the intensity of light at a point on the screen where path difference is $\lambda$, is $k$ units. The intensity of light at a point, where path difference is $\lambda /3$ is

Assume that the light of wavelength is $6000\stackrel{\circ }{A}$ coming from a star. What is the resolution limit of a telescope whose objective has a diameter of $100$ inch?

In a stạck of three polarising sheets, the first and the third are crossed while the middle one has its axis at $45°$ to the axes of the other two. The fraction of intensity of an incident unpolarised beam of light that is transmitted by the stack is

The bending of beam of light around corners of obstacles is called

Light travels in a straight line because
