Free Waves MCQs with Answers
1,281 Waves MCQs from Physics, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.

- B. 150 kHz
- C. 1500 kHz
- D. 150 Hz
Explanation: Correct option is A.We know thatF = p × nF = 50 × 300F = 1500 Hz = 15 kHzAs this is a numerical thus only one option is correct.
Correct answer: 15 kHz- A. Nature of displacement= antinode, change in frequency = decrease
- B. Nature of displacement = antinode, change in frequency = increase
- C. Nature of displacement = node, change in frequency = increase
- D. Nature of displacement = node, change in frequency = decrease
Explanation: b) Nature of displacement = antinode, change in frequency = increase:This option is correct.
Correct answer: Nature of displacement = antinode, change in frequency = increase- A. V2=F/m
- B. V=F/m
- C. V*m=F
- D. V= F*m
Explanation: Option A: V^2 = F/m: This equation suggests that the square of the wave speed (V^2) is equal to the tension (F) divided by the mass per…
Correct answer: V2=F/m- A. 0.7T
- B. T
- C. 2T
- D. 3T
Explanation: Option A suggests that the period of oscillation for the new pendulum with mass 4M and length 0.49L is 0.7 times the period T of the…
Correct answer: 0.7T- A. 1 − (x 2 / xo 2 )
- B. 1
- C. (xo 2 − x 2 )
- D. ½ (x 2)
Explanation: 𝐾𝐸 = 1 2 𝑚ω 2 (𝑥 0 2 − 𝑥 2 ) 𝑇𝑜𝑡𝑎𝑙 𝐸𝑛𝑒𝑟𝑔𝑦 = 1 2 𝑚ω 2 𝑥 0 2 Dividing the two terms gives us the ratio and the solution to…
Correct answer: 1 − (x 2 / xo 2 )- A. Damped
- B. Critical
- C. Undamped
- D. Heavily damped
Explanation: There is no change in the oscillation's amplitude hence it is undamped.
Correct answer: Undamped- A. 16s
- B. 12s
- C. 8s
- D. 4s
Explanation: Since time period is proportional to the square root of length, increasing the length 4 times would cause the time period to increase only…
Correct answer: 4s- A. 1.2 s
- B. 3.4 s
- C. 7.7 s
- D. 8.1 s
- E. 9.6 s
Explanation: We will use the concept of time dilation for this question. The calculations are given below
Correct answer: 9.6 s- A. Its acceleration is directly proportional to displacement and directed towards mean position
- B. Its acceleration is inversely proportional to displacement and directed away from mean position
- C. Its acceleration is inversely proportional to displacement and directed towards mean position
- D. Its acceleration is directly proportional to displacement and directed away from mean position
Explanation: A body executes SHM if the acceleration produced is directly proportional to the displacement and directed toward the mean position.
Correct answer: Its acceleration is directly proportional to displacement and directed towards mean position- A. 16 bits
- B. 32 bites
- C. 64 bits
- D. 128 bits
Explanation: IPv4, or Internet Protocol version 4, uses a 32-bit addressing scheme. This means that each IPv4 address is made up of 32 bits, which…
