What happens to light during total internal reflection?
The angle of incidence is greater than the critical angle.
The angle of reflection is the same as the critical angle.
The angle of refraction is less than the critical angle.
The angle of incidence is zero.
When angle of incident (i) equals to critical angle (c) if light is traveled from a denser medium to a less dense medium,
total internal reflection occurs.
angle of refraction is equal to 90 degree.
light is refracted out
light travel in straight line
Chose the TWO conditions are NOT correct for total internal reflection to take place
The incident angle should be less than the critical angle
The incident angle should be greater than the critical angle
Light should travel from a denser to a lighter medium
Light should travel from a lighter to a denser medium
What is total internal reflection
Where a wave is refracted at the boundary between a dense medium and a less dense medium when the angle of incidence is greater than the critical angle.
Where a wave is refracted at the boundary between a dense medium and a less dense medium when the angle of incidence is smaller than the critical angle.
Where a wave is reflected at the boundary between a dense medium and a less dense medium when the angle of incidence is greater than the critical angle.
Where a wave is reflected at the boundary between a dense medium and a less dense medium when the angle of incidence is smaller than the critical angle.
