The fundamental frequency of a sonometer wir carrying a block of mass '$$M$$' and density '$$\rho$$' is '$$n$$' Hz. When the block is completely immerse in a liquid of density '$$\sigma$$' then the new frequency will be

$$\mathrm{n}\left[\frac{\rho-\sigma}{\rho}\right]^{\frac{1}{2}}$$

$$\mathrm{n}\left[\frac{\rho-\sigma}{\sigma}\right]^{\frac{1}{2}}$$

$$\mathrm{n}\left[\frac{\rho}{\rho-\sigma}\right]^{\frac{1}{2}}$$

$$n\left[\frac{\sigma}{\rho-\sigma}\right]^{\frac{1}{2}}$$

Array of light is incident at an angle of incidence '$$i$$' on one surface of a prism of small angle $$\mathrm{A}$$ and emerges normally from the other surface. If the refractive index of the material of the prism is '$$\mu$$', then the angle of incidence is equal to

$$\frac{\mathrm{A}}{2 \mu}$$

$$\frac{\mathrm{A} \mu}{2}$$

$$\mathrm{A} \mu$$

$$\frac{\mathrm{A}}{\mu}$$
