10 Questions
What is the condition for total internal reflection to occur?
The waves must be incident at a sufficiently oblique angle and the second medium must have a higher wave speed
What types of waves can undergo total internal reflection?
Electromagnetic waves, sound and water waves
What happens to waves at the interface during total internal reflection?
They are completely reflected back into the first medium
In a medium whose properties are independent of direction, how is the reflection described when the waves are capable of forming a narrow beam?
In terms of rays
What is an example of an environment where total internal reflection can be observed?
A fish tank viewed obliquely from below
What is the relationship between wave speed and refractive index in the context of total internal reflection?
Higher wave speed corresponds to lower refractive index
In total internal reflection, where do the waves return after reaching the interface?
They are completely reflected back into the first medium
What is the effect of total internal reflection on the brightness of the reflected scene?
The brightness remains unchanged
What determines the description of reflection in terms of 'rays' rather than 'waves'?
The capability of waves to form a narrow beam
Under what condition does total internal reflection occur?
When the waves are incident at a sufficiently oblique angle on the interface
