What is the dual nature of radiation and matter?

The dual nature refers to the concept that both electromagnetic radiation (like light) and matter (like electrons) exhibit properties of both waves and particles, depending on the experiment being conducted. This is a key concept for Engineering 2026 physics preparation.

What is the photoelectric effect?

The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. It demonstrates the particle nature of light (photons).

What is the de Broglie wavelength?

The de Broglie wavelength is the wavelength associated with any moving particle. It proposes that matter, like particles, also has wave-like properties, with the wavelength inversely proportional to its momentum.

What is the difference between the wave nature and particle nature of light?

Wave nature explains phenomena like reflection, refraction, interference, and diffraction. Particle nature (photons) explains phenomena like the photoelectric effect and black-body radiation.

What is stopping potential?

Stopping potential is the minimum negative potential applied to an electrode in a photocell to stop the emission of photoelectrons. It is directly related to the energy of the incident photons.

Does a photon have mass?

While a photon has no rest mass, it does possess relativistic mass due to its energy and momentum, which is relevant when considering its interactions.

Why are these MCQs important for the Engineering 2026 exam?

Mastering these fundamental concepts and practicing MCQs like these is essential for building a strong foundation in physics and performing well in the competitive Engineering 2026 examinations.
