1. State true or false :
The light ray below the water undergo deviation at the surface of the water.
a. TRUE
b. FALSE
2. What happens to the path of light?
a. Path of light does not deviate.
b. Path of light undergoes deviation
3. Where does the deviation of the ray take place?
a. At the point on the surface where the OHP sheet is placed.
b. At the point on the surface where the media get separated.
c. At the bottom of the vessel.
d. None of these
4. Why does the ray of light undergo a deviation here?
a. The difference in speed of light rays in different media.
b. The speed of light rays in same media.
c. Both A and B
d. None of these.
5. Does light pass through all the media at the same speed?
a. YES
b. NO
