FAQs on Dual Nature of Matter and Radiation – JEE Main 2025-26 Mock Test Preparation
1. What is meant by the dual nature of radiation and matter?
The dual nature of radiation and matter refers to the fact that both light (radiation) and matter exhibit both particle-like and wave-like properties. For example, light shows wave behavior in phenomena like interference and diffraction, and particle behavior as photons in the photoelectric effect. Similarly, electrons and other material particles display wave properties in experiments like electron diffraction, as proposed by De Broglie.
2. What is De Broglie's hypothesis?
De Broglie's hypothesis states that every moving particle is associated with a wave, and the wavelength (λ) of this wave is given by λ = h/p, where h is Planck's constant and p is the momentum of the particle. This explains the wave nature of matter, especially significant for microscopic particles like electrons.
3. State the experimental evidence supporting the wave nature of electrons.
The wave nature of electrons was first demonstrated by the Davisson-Germer experiment, which showed that electrons, when passed through a crystal, produced a diffraction pattern similar to that produced by X-rays. This verified De Broglie's prediction of matter waves.
4. What is the photoelectric effect and how does it support the particle nature of light?
The photoelectric effect occurs when light of sufficient frequency strikes a metal surface and ejects electrons. This can only be explained if light behaves as particles (photons) which deliver energy in discrete packets, supporting the particle nature of radiation, as explained by Einstein.
5. Write the equation for De Broglie wavelength associated with a particle.
The De Broglie wavelength (λ) associated with a particle of mass m and velocity v is: λ = h/(mv), where h is Planck's constant. This equation relates the wave nature to the particle's properties.
6. How does increasing the velocity of a particle affect its De Broglie wavelength?
As the velocity (v) of a particle increases, its momentum (p = mv) increases, so the De Broglie wavelength (λ = h/(mv)) decreases. Thus, faster particles have shorter wavelengths.
7. List two differences between the wave nature of light and matter waves.
1. Light waves are electromagnetic waves that can travel through a vacuum, while matter waves are related to particles like electrons.
2. The wavelength of light is typically much larger than that of matter waves for macroscopic objects, making matter waves significant only for microscopic particles.
8. What is the significance of the dual nature of matter and radiation for JEE aspirants?
Understanding the dual nature of matter and radiation is crucial as it forms the basis for modern quantum mechanics and is an important topic in JEE Physics syllabus. Questions may test theoretical concepts, equations, and applications related to De Broglie waves, photoelectric effect, and related experiments.
9. How can the dual nature of matter be experimentally verified?
Experimental verification of dual nature comes from diffraction experiments like the Davisson-Germer experiment, which demonstrated that electrons produce an interference pattern consistent with wave behavior, in agreement with De Broglie theory.
10. What is the relation between the kinetic energy and De Broglie wavelength of an electron?
For an electron with kinetic energy (K), the De Broglie wavelength can be expressed as:
λ = h / √(2mK), where h is Planck's constant and m is the electron's mass. This shows that higher kinetic energy results in a shorter wavelength.
11. Dual nature of radiation and matter in Hindi
द्रव्य और विकिरण का द्वैत स्वभाव का अर्थ है कि दोनों ही, अर्थात, प्रकाश (विकिरण) और द्रव्य, कण और तरंग दोनों के गुण प्रदर्शित करते हैं। प्रकाश में द्रव्य का व्यवहार फोटोइलेक्ट्रिक प्रभाव में तथा तरंग व्यवहार व्यतिकरण एवं विवर्तन में देखा जाता है। द्रव्य (जैसे इलेक्ट्रॉन) में दे ब्रॉयल तरंग व्यवहार का प्रमाण डैविसन-गर्मर प्रयोग द्वारा मिलता है।
12. What are important objective questions for dual nature of matter and radiation in JEE?
Key objective questions asked in JEE are:
1. State the De Broglie hypothesis.
2. Write the formula for De Broglie wavelength.
3. Describe the photoelectric effect.
4. Explain results of the Davisson-Germer experiment.
5. Discuss the significance of dual nature in quantum mechanics.
Practicing these will help strengthen your understanding and score well in JEE Physics.
