Waves MCQs from the NET-pattern papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · NUST NET Past Paper 07 · Waves
A sound wave of frequency 500 Hz has a wavelength of 0.68 m. Its speed is:
- A.340 m/s
- B.734 m/s
- C.500 m/s
- D.170 m/s
Show answer
Answer: A. 340 m/s — v = fλ = 500 × 0.68 = 340 m/s.
- Q2 · NUST NET Past Paper 08 · Waves
Sound waves travelling through air are:
- A.transverse
- B.longitudinal
- C.electromagnetic
- D.always stationary
Show answer
Answer: B. longitudinal — Sound in air is a longitudinal mechanical wave.
- Q3 · NUST NET Past Paper 05 · Waves
A pipe open at both ends can produce:
- A.all harmonics, both odd and even
- B.only the odd harmonics
- C.only the even harmonics
- D.only its fundamental frequency
Show answer
Answer: A. all harmonics, both odd and even — An open pipe has antinodes at both ends, so all harmonics f, 2f, 3f, … are produced.
