Total internal reflection occurs when light travels from a denser medium to a rarer medium, with an angle of incidence greater than the critical angle (Option B). This optical phenomenon happens because the refractive index of the denser medium is higher, causing light to slow down. As the angle of incidence increases, there is a specific angle, called the critical angle, at which the refracted light would travel along the boundary. When the angle of incidence exceeds this critical angle, no refraction occurs, and all the light is reflected back into the denser medium. This reflection is known as total internal reflection. It is utilized in various applications, including optical fibers, where light signals are transmitted over long distances with minimal loss. The principle also explains phenomena like the sparkling effect in diamonds and the functioning of certain types of prisms.
When a ray of light travels from a rarer medium to a denser medium, it gets bent towards the normal (Option B). This phenomenon is due to the change in speed as light enters a denser medium, such as from air to water or glass. In the rarer medium, light travels faster, but upon entering the denser mRead more
When a ray of light travels from a rarer medium to a denser medium, it gets bent towards the normal (Option B). This phenomenon is due to the change in speed as light enters a denser medium, such as from air to water or glass. In the rarer medium, light travels faster, but upon entering the denser medium, its speed decreases. This change in speed causes the light to bend towards the normal line, which is an imaginary line perpendicular to the surface at the point of incidence. The degree of bending depends on the refractive indices of the two media and the angle of incidence. This behavior of light is described by Snell’s Law, which mathematically relates the angles of incidence and refraction to the refractive indices. This bending is crucial in various optical applications, such as lenses and prisms.
A stick immersed in water appears bent due to the refraction of light (Option C). Refraction occurs when light changes speed and direction as it passes from one medium to another, such as from water to air.

A stick immersed in water appears bent due to the refraction of light (Option C). Refraction occurs when light changes speed and direction as it passes from one medium to another, such as from water to air. This change in speed causes the light rays to bend at the interface between the two media. For an observer, this bending results in a shift in the apparent position of the stick. The part of the stick submerged in water appears to be at a different angle compared to the part above the surface, creating the illusion that the stick is bent. This optical phenomenon is influenced by the refractive indices of water and air and the angle at which the light enters and exits the water. As a result, the stick appears displaced and bent at the water’s surface, demonstrating the effects of refraction.
An object above the water surface appears to be at a higher height than its actual position to a person underwater due to the refraction of light (Option A).

An object above the water surface appears to be at a higher height than its actual position to a person underwater due to the refraction of light (Option A). Refraction occurs when light passes from one medium to another, such as from air to water. As light travels from the less dense medium (air) to the denser medium (water), it bends towards the normal line. This bending of light alters the perceived position of objects, making them appear higher than they truly are. The degree of this optical distortion depends on the angle of incidence and the refractive indices of the two media. For an observer underwater, this refraction shifts the apparent location of objects above the surface, leading to a visual effect where they seem elevated. This phenomenon is a common optical illusion experienced when looking up at objects from beneath the water.
Due to impurities, the boiling point (B.P) of a liquid increases. This phenomenon, known as boiling point elevation, is a colligative property observed in solutions.

Due to impurities, the boiling point (B.P) of a liquid increases. This phenomenon, known as boiling point elevation, is a colligative property observed in solutions. When a solute is added to a solvent, it lowers the vapor pressure of the solution compared to that of the pure solvent. As a result, a higher temperature is required for the vapor pressure of the solution to match the atmospheric pressure, leading to an increase in the boiling point. This effect is proportional to the concentration of the solute particles and is independent of their identity, making it a useful tool in various fields such as chemistry, biology, and industry. Boiling point elevation is utilized in processes like boiling water with salt to cook food faster or in antifreeze solutions for vehicles, where adding solutes to water raises its boiling point, preventing it from boiling off in the engine’s high-temperature environment. Therefore, due to impurities, the boiling point of a liquid increases.
