Huygens wave theory:
Huygen's wave theory is not correct in all respects.
2. It assumes simply that light energy is propagated as a wave.3. At the time of his proposition Huygen's did not have any idea about wavelength or about the transverse nature of light.4. So Huygens wave theory was Later modified by Thomas Young and Fresnel.5. They introduced the concept of wavelength and assumed that light waves are transverse.6. By these assumptions they could successfully explain not only the rectilinear propagation of light but also the phenomena of interference, diffraction and polarization of light.

Invoke the boundary condition Φ '(0)=0 to obtain a power series where the powers of x are multiples of 3.
Q. Can you define Solar Constant? The luminosity of the Sun L is 3.827×10 26 Watts. When the Sun is straight overhead on a clear day how many watts would we expect to illumina
Q State Lenz's law. Lenz's law declares that the induced current produced in a circuit always flows in such a direction that it opposes the change or cause that produces it.
Illustrate the source of stellar energy. Describe the carbon-nitrogen cycle and proton - proton cycle occurring in stars. Write down a note on ‘Breeder reactor'.
