Physics · Total internal reflection and its applications, magnification, power of a lens, combination of thin lenses in contact
For a total internal reflection, which of the following is correct?
For a total internal reflection, which of the following is correct?
- A. Light travel from rarer to denser medium
- B. Light travel from denser to rarer medium.
- C. Light travels in air only.
- D. Light travels in water only.
Step-by-step solution
Total internal reflection occurs only when light travels from a denser to a rarer medium (e.g., from water to air) and the angle of incidence is greater than the critical angle. It does not occur when light travels from rarer to denser, nor is it limited to only air or only water.
