Question

Distinguish between reflection of light and total reflection of light physics 1

Answer 1

Light travels in straight lines and therefore reflects off any hard surface. A mirror is hard and shiny so the integrity of the reflected light is reduced only slightly whereas the light reflected from a rough, dull surface becomes mushy (diffuse) and lacks intensity. I’ll let you figure out which of those scenarios might lead to the formation of a recognisable image.

Answer 2

Answer:

reflection of light

• Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated.
• Common examples include the reflection of light, sound and water waves
• Reflection is when light bounces off an object.
• If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection
• Reflection of Light. Reflection: When light falls on a shiny surface, it bounces back. This phenomenon is called reflection.

total reflection of light

• Total internal reflection is the optical phenomenon in which the surface of the water in a fish-tank when viewed from below the water level, reflects the underwater scene like a mirror, with no loss of brightness
• Total internal reflection (TIR) is the phenomenon that involves the reflection of all the incident light off the boundary
• TIR only takes place when both of the following two conditions are met: the light is in the more dense medium and approaching the less dense medium
• Total internal reflection (TIR) is the optical phenomenon in which the surface of the water in a fish-tank (for example) when viewed from below the water level, reflects the underwater scene like a mirror, with no loss of brightness
• Refraction is generally accompanied by partial reflection
