When light enters glass from vacuum, then the wavelength of light

The critical angle for light going from medium $x$ to medium $y$ is $\theta$ . The speed of light in medium $x$ is $v_x$ . The speed of light in medium $y$ is

A glass slab of thickness $4 \mathrm{cm}$ contains the same number of waves as in $x \mathrm{cm}$ of water column when both are traversed by the same monochromatic light. If the refractive indices of glass and water for that light are $\frac{5}{3}$ and $\frac{4}{3}$ respectively, the value of $x$ will be

A convex lens of focal length $f$ is placed in contact with a concave lens of the same focal length. The equivalent focal length of the combination is

A thin prism $P_1$ with angle $4°$ and made from glass of refractive index $1.54$ is combined with another thin prism $P_2$ made from glass of refractive index $1.72$ to produce dispersion without deviation. The angle of prism for $P_2$ is

The refractive index of glass is $\frac{3}{2}$ and that of water is $\frac{4}{3}.$ The critical angle for a ray of light going from glass to water is

A biconvex lens $\left(R_1=R_2=20 \mathrm{cm}\right)$ has focal length equal to focal length of concave mirror. The radius of curvature of concave mirror is [R.I. of glass lens $=1.5$]

What is the magnifying power of a simple microscope of focal length $5 \mathrm{cm},$ if the image is formed at the distance of distinct vision?
