The function ${\sin }^2(\omega t)$ represents:

A Young’s double slit experiment uses a monochromatic source. The shape of the interference fringes formed on a screen is:

Two simple harmonic motions are represented by the equation $y_1=0.1\sin (100\pi t+\pi /3)$ and $y_2=0.1\cos \pi t$. The phase difference of the velocity of particle $1$ w.r.t. the velocity of the particle $2$ is:

A fish looking up through the water sees the outside world contained in a circular horizon. If the refractive index of water is $4/3$ and the fish is $12\text{ cm}$ below the surface, the radius of this circle in cm is:

Two point white dots are $1\text{ mm}$ apart on a black paper. They are viewed by eye of pupil diameter $3\text{ mm}$. Approximately, what is the maximum distance at which these dots can be resolved by the eye? [Take wavelength of light $=500\text{ nm}$ ]
