The chart shows the speed at which light travels through different media.

A 2 column by 5 row table. Column 1 is titled Medium and contains the following entries: Water, Air, Glass, Diamond. Column 2 is titled Speed of Light (meters per second) and contains the following entries: 2.25 times 10 Superscript 8 baseline, 2.99 times 10 Superscript 8 baseline, 1.97 times 10 Superscript 8 baseline, 1.24 times 10 Superscript 8 baseline.
In which medium would light have the longest wavelength?

C).

Explanation:

As we know that capacitance of a given capacitor is

now we know that energy stored in the capacitor plates

here if all the dimensions of the capacitor plate is doubled

then in that case

here area becomes 4 times on doubling the radius and the distance between the plates also doubles

So new capacitance is now

so capacitance is doubled

now the final energy stored between the plates of capacitor is given as

so the final energy is
