A light ray falls on the interface between air and water. Under what conditions will the ray of light undergo total internal reflection?
- AThe ray, initially in the air, is incident on the air-water boundary at any angle of incidence.
- BThe ray, initially in the air, is incident on the air-water boundary at an angle of incidence greater than the critical angle.
- CThe ray, initially in the water, is incident on the water-air boundary at any angle of incidence.
- DThe ray, initially in the water, is incident on the water-air boundary at an angle of incidence greater than the critical angle.
