Applications of Total Internal Reflection Quiz

What is the primary function of optical fibers in telecommunications?

• To reflect light
• To transmit light pulses carrying information
• To bend light
• To separate colors of light

How does total internal reflection occur in optical fibers?

• When light strikes at an angle less than the critical angle
• When light strikes at an angle greater than the critical angle
• When light travels through air
• When light is absorbed by the fiber

What is the role of the bundle of fibers in a medical endoscope?

• To increase the speed of light
• To allow bending without breaking
• To reflect light
• To change the color of light

What angle do the prisms used in periscopes typically have?

What is the critical angle?

• The angle at which light is absorbed
