Answer to Problem 1CQ
The frequency remains same even if the medium is changed.
Explanation of Solution
Frequency is defined as number of oscillations per second. The solution can be understood from the concept of sound wave in different medium.
Sound wave in air creates some oscillations back and forth. As it enters the water, it pushes the surface of water creating compressions the sound wave the moves to water with the same frequency as that in air.
The same concept applies in light wave entering the glass. Hence, the frequency of wave remains same as the wave changes its medium of traversal.
Conclusion:
Thus, the frequency remains same even if the medium is changed.
