How to Solve NCERT Questions?

Firstly Read Questions from Book & then write down the given data in Notebook & also mark What you have to find out?

If any Value is given other than S. I then change that digit in S. I.

Now think About formula which you can apply in given question.

Now Solve question if your answer is correct then try next if not check solution provided by Sciphy & try again. Similarly try next question.

All Topics of Wave Optics are Equally Important.

•Huygen’s Theory

•Interference

•Diffraction

wave front and Hudgens Principle, reflection and refraction of plane Wave at a plane surface using Wavefronts. Proof of Laws of Reflection and Refraction using Huygen’s principle. Interference, Young’s double slit Experiment and expression for fringe width( No derivation final expression only) , Coherent sources and sustained interference of light, Diffraction due to a single slit, width of central maxima ( Qualitative treatment only).

Wavefront: It is locus of all particles Vibrating in same phase.

for Point source shape of wavefront will be spherical wavefront. For line source Shape of wavefront will be Cylendrical & when source of light will be at infinite distance apart shape of wavefront will be plane. Direction of wavefront can be represented by rays, perpendicular to Wave front.According to Huygen’s Theory each point on the primary wavefront act as a source of secondary wavelets & tangent drawn on secondary wavelets will give secondary wavefront in forward direction.

Interference :

Non – Uniform distribution of energy in a medium when light coming from two different sources.

for interference sources must be coherent.

Coherent sources:

Two sources are said to be coherent if they have the same frequency and wavelength, which means that the waves produced by these sources maintain a predictable relationship with each other over time. Amplitude may or may not be the same; however, the important aspect of coherence is the consistency in the phase of the waves. The phase difference between the two sources must be zero, or there should be a constant phase difference maintained throughout their oscillation, ensuring that the waves constructively or destructively interfere with one another in a stable manner. This stability in phase difference is crucial for producing clear and distinct interference patterns, which can be observed in various phenomena such as young’s double-slit experiment, where light waves from coherent sources create alternating bright and dark fringes, demonstrating the wave nature of light and the fundamental principles of interference.

Why Coherent sources are necessary for Interference?

For Sustained Interference means for permanent pattern.
