✨ Waves — ReNEET 2026-Style Reasoning Questions

The newest, most exam-current physics format — reasoning-based questions modelled on ReNEET 2026. Practise where NEET is heading before the exam does.

Q1. Two transverse waves on separate strings are described by $y_{1} = A sin (2 x - 8 t)$ and $y_{2} = A sin (4 x - 8 t)$ (all in SI units). The ratio of their wave speeds $v_{1} : v_{2}$ is:
Q2. The figure shows a snapshot of a transverse wave on a string at one instant. The wave is moving in the $+ x$ direction. At this instant, in which direction is the marked particle P (currently at the mean position) moving?
Q3. Two non-magnetic media have relative permittivity $ε_{r 1} = 2$ and $ε_{r 2} = 8$ . The same light wave can travel in both. What is the ratio of its speed in the first medium to its speed in the second medium, $v_{1} : v_{2}$ ?
Q4. A capacitor with circular plates of radius $R = 4 cm$ is charged by a steady current $i = 8 A$ . Find the magnitude of the magnetic field between the plates at radius $r = 2 cm$ , and the ratio of this field to the field at the plate edge ( $r = R$ ). (Take $μ_{0} = 4 π \times 1 0^{- 7} T m A^{- 1}$ .)
Q5. In an electromagnetic wave, how does the average energy density of the electric field compare with that of the magnetic field?
Q6. A parallel-plate capacitor is being charged at a steady rate. Consider two statements. Statement I: The displacement current between the plates has the same magnitude as the conduction current in the connecting wire. Statement II: The sum $(i_{c} + i_{d})$ has the same value for every surface bounded by a given Amperian loop, so the total current is continuous throughout the circuit. Choose the correct option.
Q7. Assertion (A): When the same beam of light is incident at a fixed angle from air, it bends more toward the normal on entering glass ( $n = 1.5$ ) than on entering water ( $n = 1.33$ ). Reason (R): The medium with the higher refractive index has the smaller wave speed, so by Huygens' construction its secondary wavelets travel a shorter distance in a given time and the wavefront turns more sharply toward the normal.
Q8. The entire Young's double-slit apparatus is immersed in a transparent liquid of refractive index $n$ $(> 1)$ . Compared with the situation in air, which statement about the pattern is correct?
Q9. A plane wavefront passes through (I) a thin prism and (II) a thin convex lens. How does the emergent wavefront differ in the two cases?
Q10. In a two-slit interference pattern the amplitudes of the two interfering waves are in the ratio $3 : 1$ . The ratio of the maximum to the minimum intensity, $I_{m a x} : I_{m i n}$ , is:

🔢 Waves — Numericals — PYQ-Based

Exam-style numericals seeded from real NEET previous-year questions, kept inside the NEET syllabus boundary. Each with a worked solution.

Q1. Two coherent waves of wavelength λ meet at a point with a path difference of λ/4. The corresponding phase difference between them is:
Q2. A transverse harmonic wave traveling on a string is described by the equation y(x,t) = 0.05 sin[(4π)(2t - x/3)], where all quantities are in SI units. What is the wavelength of the wave?
Q3. A guitar string of fundamental frequency 320 Hz is tuned by adjusting tension. When plucked simultaneously with a tuning fork of unknown frequency, beats of frequency 8 Hz are heard. The tension in the string is then increased by 5%, and the beat frequency changes to 4 Hz. A second tuning fork of frequency 340 Hz is now sounded with the newly tuned string, producing beats. What is the beat frequency heard with the second tuning fork?
Q4. A stationary observer is positioned between two moving sources of sound. Source A is approaching the observer from the left at 20 m/s and emits sound at 600 Hz. Source B is receding from the observer towards the right at 15 m/s and emits sound at frequency fB. The observer hears a beat frequency of 4 Hz. Taking the speed of sound as 340 m/s, and given that the apparent frequency from source A is higher than that from source B, the frequency fB emitted by source B is:
Q5. An X-ray tube operates at an accelerating potential of 12.4 kV. What is the minimum wavelength of X-rays produced? (Take h = 6.6 × 10⁻³⁴ J·s, c = 3 × 10⁸ m/s, e = 1.6 × 10⁻¹⁹ C)
Q6. The electric field in a plane electromagnetic wave is given by: E = 30 sin(4π × 10⁶ x - 12π × 10¹⁴ t) ẑ V/m. What is the wavelength of this electromagnetic wave?
Q7. An electromagnetic wave propagating in vacuum has an electric field amplitude of 90 V/m. What is the amplitude of the magnetic field component of this wave? (Given: speed of light c = 3 × 10⁸ m/s)
Q8. In a Young's double slit experiment, when monochromatic light of wavelength 600 nm is used in air, the fringe width on a screen placed at distance D is measured to be β. The entire experimental setup is now placed inside a transparent liquid of refractive index μ = 1.5. Subsequently, the slit separation is reduced to half of its original value while keeping the screen distance unchanged. If the angular width of each fringe (measured from the midpoint of the two slits) in the liquid medium is observed to be 0.3°, what was the original angular width of each fringe in air?
Q9. A beam of unpolarised light of intensity I₀ is incident on a polaroid A. It then passes through a second polaroid B whose axis makes an angle of 30° with the axis of A, and finally through a third polaroid C whose axis makes an angle of 60° with the axis of B. What is the intensity of light emerging from polaroid C?
Q10. A Young's double slit experiment is performed first in air and then the entire apparatus (slits and screen) is immersed in a transparent liquid of unknown refractive index. It is observed that the 4th bright fringe from the central maximum in air now coincides in position with the 6th bright fringe from the central maximum in the liquid. When the experiment is repeated with the apparatus back in air but with a thin glass plate (refractive index 1.5) of thickness t placed in front of one of the slits, the central bright fringe shifts to the position originally occupied by the 3rd bright fringe. The refractive index of the liquid is:
