An initially parallel cylindrical beam travels in a medium of refractive index $\mu (I)={\mu }_0+{\mu }_{2}I$, where ${\mu }_0$ and ${\mu }_2$ are positive constants and $I$ is the intensity of the light beam. The intensity of the beam is decreasing with increasing radius. As the beam enters the medium, it will:

An initially parallel cylindrical beam travels in a medium of refractive index $\mu (I)={\mu }_0+{\mu }_{2}I$. The initial shape of the wave front of the beam is:

An initially parallel cylindrical beam travels in a medium of refractive index $\mu (I)={\mu }_0+{\mu }_{2}I$. The speed of light in the medium is:

A small particle of mass $m$ is projected at an angle $\theta$ with the $x$ -axis with an initial velocity $v_0$ in the $x-y$ plane. At a time $t<\frac{v_0\sin \theta }{g}$, the angular momentum of the particle about the origin is:

The equation of a wave on a string of linear mass density $0.04{\text{kg m}}^{-1}$ is given by $y=0.02(m)\sin [2\pi (\frac{t}{0.04(s)}-\frac{x}{0.50(m)})]$. The tension in the string is:
