Diffraction leads to the formation of patterns of varying intensity. When around obstacles, waves bend and spread through the narrow opening, it is called diffraction. The interference results in a new wave pattern and involves the superposition of two or more coherent waves. Both these phenomena produce patterns of light and dark regions; the interference results from the combination of multiple waves and the diffraction arises from a single wave interacting with an aperture or obstacle. When the size of the aperture or obstacle is comparable to the wavelength of the wave, diffraction patterns are typically observed.

A coherent light source in Young's Double Slit Experiment illuminates two closely spaced slits, and produces two overlapping light waves. The interference of these waves constructively or destructively based on their phase difference lead to a pattern of bright and dark fringes on a screen, When the path difference is an integral multiple of the wavelength, it is constructive interference (bright fringes) and when the path difference is an odd multiple of half the wavelength, it is destructive interference (dark fringes). Through observable interference patterns, Young's Double Slit Experiment, shows the wave nature of light.

According to Chapter 10 Physics Class 12, the Huygens' Principle in wave optics states that every point on a wave front spreads out in all directions at the speed of the wave, and these act as a source of secondary wavelets. According to this principle, all new wave front is the tangent to these secondary wavelets. The principle holds significance when it comes to explaining phenomena like refraction and reflection of light. It is instrumental in understanding the behavior of light in various media and provides a geometric method to determine the propagation of wave fronts. The Huygens' Principle lays the foundation for the wave theory

With a rank of 15,000 the chances of getting a preferred course or a college becomes very high. A rank of 15,000 in JEE Main 2024 exam is considered to be a high / top rank in JEE 2024 Mains exam keeping in mind the level of difficulty that is maintained every year by the National Testing Agency. With the rank of 15,000 candidates can expect to get admission in a most of the popular NITs, IIITs and GFTIs through the JoSAA Counselling process.

NTA has conducted both sessions of the JEE Main 2025 exam. Session 1 was held from Jan 22, 2025 to Jan 30, 2025. Moreover, the JEE Main Session 2 exam was held between Apr 2 and Apr 8, 2025 (except Apr 5 & Apr 6). Students who couldn't appear for the exam can apply via other exams, such as the SAT and MH-CET.

Electromagnetic waves do not require a medium to propagate because they generate self-sustaining oscillations of magnetic and electric fields. Hence, it can travel through the vacuum of space. A changing magnetic field generates an electric field and vice versa. This property allows the wave to carry energy across space. The phenomenon is applicable to sunlight and other forms of EM radiation that travel through space to reach Earth. They cover millions of kilometers while reaching Earth. The EM wave theory is fundamental to understanding phenomena like cosmic observations, satellite communication, and solar radiation.
