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.

JIPMER Puducherry admits candidates to BSc courses based on merit from the NEET exam. To secure admission, candidates must take the NEET examination and achieve the required ranks and scores. However, according to some unofficial sources, certain BSc programs, such as BSc in Cardiac Laboratory Technology at JIPMER Puducherry, may not require NEET scores for admission. Candidates are advised to carefully review the eligibility and selection criteria before applying to these courses.

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.

The NEET OMR response sheet refers to candidates' answer sheets or OMR sheets where they have marked their responses. On the other hand, the provisional answer keys refer to correct answer options according to NTA experts. The NEET OMR response sheets of candidates are scanned and uploaded on the official website of the exam which candidates can download and check for discrepancies. Candidates are also advised to note down their own responses or answer options marked to calculate their estimated scores. 

The NEET 2025 OMR response sheet was released on June 3, 2025. Within this, candidates can check their OMR sheets or response sheets where they had marked answers in. In case of any discrepancy on the response sheet, candidates could submit obections or challenges to NTA by June 5, 2025, 11.50 PM. Along with the OMR sheet, NTA also released the provisional NEET answer keys. Candidates could submit objections against either or both documents. They could also calculate the estimated scores by crosschecking their responses on the NEET OMR sheet and the answer keys.
