MHT CET 2022 11th August Evening Shift | Ray Optics Question 62 | Physics

The speed of light in two media $$M_1$$ and $$M_2$$ are $$1.5 \times 10^8$$ $$\mathrm{m} / \mathrm{s}$$ and $$2 \times 10^8 \mathrm{~m} / \mathrm{s}$$ respectively. If the light undergoes total internal reflection, the critical angle between the two media is

$$\sin ^{-1}\left(\frac{3}{2}\right)$$

$$\sin ^{-1}\left(\frac{2}{3}\right)$$

$$\sin ^{-1}\left(\frac{4}{3}\right)$$

$$\sin ^{-1}\left(\frac{3}{4}\right)$$

A ray of light is incident on one face of an equilateral glass prism having refractive index $$\sqrt{2}$$. It produces the emergent ray which just. grazes along the adjacent face. The value of angle of incidence is $$\left(\sin 45^{\circ}=\cos 45^{\circ}=\frac{1}{\sqrt{2}}\right)$$

$$\sin ^{-1}\left(\frac{1}{\sqrt{2}} \sin 15^{\circ}\right)$$

$$\sin ^{-1}\left(\sqrt{2} \sin 30^{\circ}\right)$$

$$\sin ^{-1}\left(\frac{1}{\sqrt{2}} \sin 45^{\circ}\right)$$

$$\sin ^{-1}\left(\sqrt{2} \sin 15^{\circ}\right)$$

White light consists of wavelengths from $$480 \mathrm{~nm}$$ to $$672 \mathrm{~nm}$$. What will be the wavelength range when white light is passed through glass of refractive index 1.6?

$$420 \mathrm{~nm}-672 \mathrm{~nm}$$

$$300 \mathrm{~nm}-480 \mathrm{~nm}$$

$$300 \mathrm{~nm}-420 \mathrm{~nm}$$

$$300 \mathrm{~nm}-672 \mathrm{~nm}$$
