JEE Main PYQs on Radiation: JEE Main Questions for Practice with Solutions

Educational Content Expert | Updated on - Sep 4, 2025

The JEE Main Physics section requires speed and accuracy, along with a thorough understanding of the radiation. This article provides a set of JEE Main PYQs on radiation to help you understand the topic and improve your problem-solving skills with the help of detailed solutions by ensuring conceptual clarity, which will help you in the JEE Main 2026 preparation.

Whether you're revising the basics or testing your knowledge, these JEE Main PYQs will serve as a valuable practice resource.

The JEE Main 2026 exam is likely to continue on the same pattern as JEE Main 2025. Out of 90 questions, students can expect a fair mix from all three subjects. To get an edge, going through JEE Main previous year questions (PYQs) is one of the best strategies.

Parallel rays of light of intensity I=912 Wm$^{-2}$ are incident on a spherical black body kept in surroundings of temperature 300 K . Take Stefan constant $\sigma =5.7 \times 1^{-8} Wm ^{-2} K^{-4}$ and assume that the energy exchange with the surroundings is only through radiation The final steady state temperature of the black body is close to
- 330 K
- 660 K
- 990 K
- 1550 K

To verify Ohm's law, a student connects the voltmeter across the battery as, shown in the figure. The measured voltage is plotted as a function of the current, and the following graph is obtained: If $V_0$ is almost zero, identify the correct statement:
- The value of the resistance $R$ is $1.5 \,\Omega$
- The emf of the battery is $1.5\, V$ and the value of $R$ is $1.5 \, \Omega$
- The emf of the battery is $1.5\, V$ and its internal resistance is $1.5$ $\Omega$
- The potential difference across the battery is $1.5\, V$ when it sends a current of $1000\, mA$
