Is it possible to achieve total internal reflection if the object is in rarer medium?
No, total internal reflection can only occur when light travels from a denser medium to a less dense medium. If light travels from a less dense medium to a denser medium, it will refract towards the normal rather than being internally reflected.
Why does velocity of light in rarer medium than in denser medium?
Light travels faster in rarer mediums than in denser mediums because the density of the medium affects the speed at which light waves can propagate. In rarer mediums, there are fewer particles for light to interact with, allowing it to travel faster. This difference in speed is due to the change in the refractive index of the medium.
What Critical angle of light passing from glass to water is minimum from?
The critical angle of light passing from glass to water is minimum when the light is passing from a denser medium (glass) to a rarer medium (water), which is when the light travels along the normal. At this orientation, the critical angle is the smallest possible value for the glass-water interface.
How is the direction of aray of light changed when it travels from an optically denser to an optically rarer medium?
When light travels from an optically denser medium to an optically rarer medium, it bends away from the normal (angle of incidence is greater than angle of refraction) due to the decrease in the speed of light in the rarer medium. This phenomenon is known as refraction.
Is there any phase change occurred when sound wave refracted from denser medium to a rarer medium?
No, there is no phase change that occurs when a sound wave refracts from a denser medium to a rarer medium. The wavelength and frequency of the wave may change due to the change in speed, but the phase remains the same.
What is emergent ray in refraction of light?
The emergent ray is the ray of light which passes through a denser medium(glass) to a rarer medium(air).
What happenend light from rarer to denser medium?
It slowed down.

Why the lower part of air is rarer at day but denser at night?
because the sun evaporates moisture during the day, as the air cools at night it becomes denser.
What is difference between rarer and danser medium?
In denser medium,particles of matter are very close to each other.whereas,in rarer medium,particles of the medium are slightly farther apart.
Is there any phase change occurred when sound wave refracted from denser medium to a rarer medium?

When light travels from a denser medium to a rarer medium it bends away from the normal Is it possible for the light ray to reflect back in the same medium?
Yes, when light travels from a denser medium to a rarer medium and strikes the interface at an angle greater than the critical angle, total internal reflection can occur. In this case, the light ray reflects back into the denser medium instead of refracting into the rarer medium.
What does light bend when it passes from air into glass?
refraction
Why does tha refracted light bends towards the base of prism?
When light enters a denser medium from a rarer medium, it slows down, causing it to bend towards the normal. As the light exits the denser medium into the rarer medium, it speeds up and bends away from the normal. This change in speed and direction is why refraction occurs in a prism.
