Young’s double slit Experiment on Interference

Young’s double slit Experiment on Interference In 1807 famous scientist Young performed an experiment to demonstrate the interference of light. In his honor, this experiment......

Conditions for Interference of Light

If two light-waves having same frequencies and amplitudes emitted from two coherent sources pass through the same point in a medium, the point becomes very......

Interference of Light

If two light-waves having same frequencies and amplitudes emitted from two coherent sources pass through the same point in a medium, the point becomes very......

Coherent Sources of Light-wave

Coherent sources of Light-wave If light-waves of the same wavelength are emitted from two sources with a particular phase difference and it that phase difference......

Superposition of Waves

Superposition of waves: If two waves cross through a particle of a medium simultaneously, then each wave will displace that particle. As a result, there......

Laws of Refraction in the light of Huygens’s Principle

Laws of Refraction in the light of Huygens’s Principle According to Huygens’s principle, any point in the wavefront can be considered as the source of......

Laws of Reflection in the Light – Huygens’s Principle

Laws of Reflection in the Light – Huygens’s Principle Each point on any wavefront is considered as the source of oscillation or disturbance. The waves......

Huygens’s Principle – Propagation of Light Waves

Huygens’s Principle – Propagation of Light Waves If the source of light is known, then the position of wavefronts can be determined by ordinary rule.......

Plane Wave Front

Plane Wave Front The continuous locus of points having the same phase of vibration in a medium through which a wave propagates is called a......

Wave Front Explanation

Wave Front Explanation We know, disturbance in a medium is created due to the combined vibration of different particles of the medium. For example –......

Spherical Wave Fronts

Spherical wave fronts We know, the locus of the particles in a wave having the same phase is the wave front. The wave fronts near......

Electromagnetic Spectrum

Electromagnetic Spectrum The electromagnetic spectrum describes all the wavelengths of light. From dark nebulae to exploding stars, it reveals an otherwise invisible universe. Any periodic......
