11
If two notes are played, one at 300 Hz and the other at 600 Hz, how do their pitches compare?
RRB Group D
11 Aug, 2026 (4:30 PM - 6:00 PM)
2026
✓ Answer:BThe 600 Hz note has a higher pitch
The correct choice is The 600 Hz note has a higher pitch. Sound behaviour is determined by wave properties such as frequency, amplitude, wavelength and the medium of propagation.
12
Which statement is true about two sounds with the same amplitude but different frequencies?
RRB Group D
12 Aug, 2026 (9:00 AM - 10:30 AM)
2026
✓ Answer:CThey have the same loudness but different pitch
Amplitude determines loudness, while frequency determines pitch. Therefore the sounds have the same loudness but different pitch.
13
When a tuning fork vibrates and produces sound, what type of waves is created in the surrounding air?
RRB Group D
17 Aug, 2026 (12:45 PM - 2:15 PM)
2026
✓ Answer:BA longitudinal wave with compressions and rarefactions.
A vibrating tuning fork produces longitudinal sound waves in air, consisting of compressions and rarefactions.
14
If a musical instrument produces a sound with a frequency of 200 Hz, which of the following frequencies will produce a sound of higher pitch than this instrument?
RRB Group D
11 Aug, 2026 (12:45 PM - 2:15 PM)
2026
✓ Answer:D350 Hz
Pitch depends on frequency. A frequency higher than 200 Hz produces a higher-pitched sound.
15
If two sounds have the same frequency but different amplitudes, what will be different?
RRB Group D
14 Aug, 2026 (4:30 PM - 6:00 PM)
2026
✓ Answer:BTheir loudness will be different
With frequency unchanged, pitch is unchanged; changing amplitude changes loudness.
16
If the frequency of a sound wave increases while its speed in air remains constant, what happens to its wavelength?
RRB Group D
25 Aug, 2026 (9:00 AM - 10:30 AM)
2026
✓ Answer:BIts wavelength decreases
The correct choice is Its wavelength decreases. Sound behaviour is determined by wave properties such as frequency, amplitude, wavelength and the medium of propagation.
17
Which statement best explains the difference between a low pitch sound and a high pitch sound?
RRB Group D
20 Aug, 2026 (4:30 PM - 6:00 PM)
2026
✓ Answer:CA low pitch sound has a lower frequency compared to a high pitch sound.
The correct choice is A low pitch sound has a lower frequency compared to a high pitch sound.. Sound behaviour is determined by wave properties such as frequency, amplitude, wavelength and the medium of propagation.
18
A group of engineers is tasked with designing a lecture hall for maximum speech intelligibility. Which combination of features should they prioritize to minimize reverberation?
RRB Group D
19 Aug, 2026 (9:00 AM - 10:30 AM)
2026
✓ Answer:CSoft wall coverings, acoustic ceiling tiles, and upholstered seating
Excessive reverberation causes successive reflections to overlap, making speech less distinct and harder to understand.
19
A sound wave has a frequency of 500 Hz and travels at 340 m/s. What is its wavelength?
RRB Group D
20 Aug, 2026 (4:30 PM - 6:00 PM)
2026
✓ Answer:AIts wavelength is 0.68 meters
Using v = fλ, λ = 340/500 = 0.68 m.
20
Why can humans NOT hear the sound produced by a bat?
RRB Group D
14 Aug, 2026 (9:00 AM - 10:30 AM)
2026
✓ Answer:DThe frequency of bat sounds is above 20,000 Hz.
The correct choice is The frequency of bat sounds is above 20,000 Hz.. Sound behaviour is determined by wave properties such as frequency, amplitude, wavelength and the medium of propagation.
