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

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.

The entire range of electromagnetic radiation, arranged to increase and decrease the wavelength is called the electromagnetic (EM) spectrum. In the following order, it includes - radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. All these regions have unique properties and applications. For example, X-rays used in medical imaging, visible light in everyday vision, infrared in remote controls and thermal imaging and radio waves are used in communication. This is an important concept that helps in classifying and utilizing different EM waves.

Although the cutoff will be calculated after the declaration of results but according to past trends, cutoff for General students was around 90 percentile, so assuming this year the same trend will be followed. However getting addmission in good institute doesn't depends on only CAT score. You need to score good marks in class 10th and 12th and graduation as well. Personal interview plays a major role for getting admission.
