Can you help with 9a and 9b please 9a. A ray of light, emitted beneath the surface of an unknown liquid with air above it, undergoes total internal reflection as shown in the figure below. What is the index of refraction for the liquid and its likely identification? 9b. The substance is most likely _____ a. benzene b. carbon disulfide c. carbon tetrachloride d. ethanol e. glycerine f. water
Applications Of Reflection Of Light
When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.
Sign Convention for Mirrors
A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
