Which of the following phenomena conclusively proves that electromagnetic waves are transverse in nature?

In interference and diffraction, light energy is redistributed. If it reduces in one region (dark fringe), it increases in another region (bright fringe). A. As there is no net gain or loss of energy, these phenomena are consistent with the principle of conservation of energy. B. Diffraction and interference are characteristics exhibited only by light waves. Choose the correct option:

Two waves of intensity I and 4I produce a resultant intensity of 5I in an interference experiment. What is the phase difference between the two waves?

In a single-slit diffraction experiment, the first minimum for red light coincides with the first secondary maximum of light of another wavelength λ2. If the wavelength of red light is 3000 Å, then the wavelength λ2 is:

In Young's double-slit experiment, if the distance between the slits is halved and the distance between the plane of slits and the screen is doubled, the fringe width will become:

Which phenomenon confirms that light waves are transverse in nature?

If the amplitudes of two interfering waves are in the ratio 1:2, then the ratio of maximum to minimum intensity in the interference pattern will be:

In Young's double slit experiment, if the distance between the slits is halved and the distance between the plane of the slits and the screen is doubled, the fringe width will become:
