Answer:
C
Explanation:
As speed decreases, if we change the medium of electromagnetic wave from air to water, frequency remains the same.
As we go from one medium to another the frequency stays the same, but the wavelength changes. Change in speed is proportional to change in wavelength.
Hope this helps. Thanks!
