What is an optically rarer medium?

(a) √3/√2 is the correct option

Highest optical density = Diamond Lowest optical density = Air Optical density of a medium is directly related with the refractive index of that medium. A medium which has the highest refractive...

A medium in which light travels comparatively slower than the other medium is called an optically denser medium.

The refractive index of alcohol is more than water, therefore, alcohol is optically denser medium.

Yes, a convergent lens in one medium becomes divergent in another medium when the refractive index of the medium is greater than the refractive index of the material of the...

(c) may move on the X-axis (d) may move on the Y-axis. EXPLANATION:   Mechanical waves are either transverse or longitudinal. In the transverse wave, the particles will move on Y-axis while in the...

(b) light goes from optically denser medium to rarer medium EXPLANATION:  When the light goes from a denser medium to lighter medium, it goes away from the normal. When the angle of...

(b) According to Snell’s Law,  sin i/ sin r =μ 2/μ 1 = where r = 90º for particular incidence angle called critical angle. When the incidence angle is equal to or greater than...

No; when light travels from a rarer to denser medium, its frequency remains unchanged. According to quantities theory, the energy of a light beam depends on frequency and not on...
