Waves NEET Questions: Waves is an important subject in NEET Physics and the basis for studying oscillatory motion and wave phenomena. The topic is included in NCERT Class 11, Chapter 14: Oscillations and Waves, and is commonly seen in the NEET Physics section. The study of waves is important to achieve high marks in NEET 2025, as it covers concepts such as wave motion, sound waves, and their characteristics. This article presents waves NEET questions with answers, including important formulas, main concepts, and practical applications. Let's get started and reinforce your NEET preparation!
The chapter Waves includes all the important topics that are transverse waves and longitudinal waves, speed of a wave, Doppler effect, and superposition of waves. These topics give trouble to most of the NEET aspirants, but with regular practice and previous year NEET questions (PYQs), it becomes easy. This chapter also provides a foundation for Wave Optics and Modern Physics in Class 12, hence it is a high-scoring topic in NEET.
The table below shows the number of waves questions that have appeared in NEET over the last 10 years:
Year | Total Questions | Easy | Medium | Hard |
2015 | 3 | 1 | 2 | 0 |
2016 | 4 | 2 | 2 | 0 |

Understanding the difficulty level of Waves questions helps students prepare strategically:
Difficulty Level | Percentage of Questions |
Easy | 30% |
Medium | 55% |
Hard | 15% |
Here are the key concepts that NEET aspirants must focus on while preparing for Waves:
Concept | Description |
Wave Motion | Propagation of disturbances in a medium or vacuum. |
Types of Waves | Transverse and longitudinal waves, examples include light waves and sound waves. |
Wave Equation | General wave equation: v = fλ (wave speed = frequency × wavelength). |
Sound Waves | Longitudinal mechanical waves require a medium for propagation. |
Doppler Effect | Frequency changes due to relative motion between source and observer. |
Superposition Principle | Interference and formation of standing waves. |
Beats | Formation of periodic variations in sound due to frequency differences. |
Resonance | Amplification of a wave when the frequency matches the natural frequency. |
Ques:1 What is the relation between velocity (v), frequency (f), and wavelength (λ) of a wave? (NEET 2024) (Difficulty: Easy)
Options:
v = f/λ
v = λ/f
v = fλ
v = 1/fλ

Answer:
The wave equation is given by v = fλ, where v is the wave velocity, f is the frequency, and λ is the wavelength. This equation is fundamental in wave mechanics. Hence, the correct answer is option (3).
Ques:2 In the Doppler effect, if the source moves towards a stationary observer, the frequency of the sound wave: (NEET 2023) (Difficulty: Medium)
Options:
Increases
Decreases
Remains the same
First increases, then decreases
Answer:
When the source moves towards a stationary observer, the apparent frequency increases due to wave compression. This is given by the Doppler Effect formula: f’ = f v+0v-vswhere v is the speed of sound and vs is the speed of the source. Hence, the correct answer is option (1).
The fundamental frequency of an open organ pipe is given by: (NEET 2022) (Difficulty: Medium)
Options:
v/2L
v/L
2v/L
v/4L
Answer:
For an open organ pipe, the fundamental frequency is given by f = v/2L, where L is the length of the pipe. Hence, the correct answer is option (1).
Ques:4 What happens when two sound waves of nearly equal frequencies interfere? (NEET 2021) (Difficulty: Medium)
Options:
Beats are formed
The frequency increases
The amplitude decreases
No effect is observed
Answer:
When two sound waves of slightly different frequencies interfere, beats are formed. The beat frequency is given by f beat = f1 - f2. Hence, the correct answer is option (1).
Ques: 5 The speed of sound is maximum in which of the following? (NEET 2020) (Difficulty: Medium)
Options:
Solids
Liquids
Gases
Vacuum
Answer:
The speed of sound is maximum in solids, followed by liquids and then gases, due to the high elasticity and density of solids. Sound cannot travel in a vacuum, as it requires a medium. Hence, the correct answer is option (1).
Study NCERT Exhaustively – NEET Physics has a lot of questions directly from NCERT.
Practice Numericals – Wave equations, Doppler effect, and sound wave properties are to be practiced.
Remember Key Formulas – All the formulas related to wave motion need to be revisited periodically.
Learn Graphs & Diagrams – Waveforms, interference patterns, and resonance diagrams.
Solve PYQs & Mock Tests – Try to find out patterns in the previous year's NEET questions.
Waves is a high-value topic under NEET Physics. Through studying wave motion, the Doppler effect, and sound waves and solving past year NEET problems, students can enhance their performance. Pay attention to important formulas, practice numericals, and try mock tests to enhance accuracy and speed. Keep practicing, and you'll ace Waves in NEET 2025!

Orthotists and Prosthetists are professionals who provide aid to patients with disabilities. They fix them to artificial limbs (prosthetics) and help them to regain stability. There are times when people lose their limbs in an accident. In some other occasions, they are born without a limb or orthopaedic impairment. Orthotists and prosthetists play a crucial role in their lives with fixing them to assistive devices and provide mobility.

The audiologist career involves audiology professionals who are responsible to treat hearing loss and proactively preventing the relevant damage. Individuals who opt for a career as an audiologist use various testing strategies with the aim to determine if someone has a normal sensitivity to sounds or not. After the identification of hearing loss, a hearing doctor is required to determine which sections of the hearing are affected, to what extent they are affected, and where the wound causing the hearing loss is found. As soon as the hearing loss is identified, the patients are provided with recommendations for interventions and rehabilitation such as hearing aids, cochlear implants, and appropriate medical referrals. While audiology is a branch of science that studies and researches hearing, balance, and related disorders.
An oncologist is a specialised doctor responsible for providing medical care to patients diagnosed with cancer. He or she uses several therapies to control the cancer and its effect on the human body such as chemotherapy, immunotherapy, radiation therapy and biopsy. An oncologist designs a treatment plan based on a pathology report after diagnosing the type of cancer and where it is spreading inside the body.
