What is the time taken for one complete oscillation of density or pressure in a sound wave called?
RRB JE
24/05/2019 (Shift-IV)
2019
✓ Answer:ATime period
The time period is the duration of one complete oscillation.
122

RRB Group-D
12/10/2018 (Shift-I)
2018
✓ Answer:DAll options
Sound can propagate through solids, liquids and gases.
123
In which state can a medium transmit sound?
RRB JE
02/06/2019 (Shift-IV)
2019
✓ Answer:DAll of these
Material media in solid, liquid or gaseous states can transmit sound.
124
What is the frequency range of ultrasonic waves?
RRB NTPC (Stage-I)
05/04/2016 (Shift-II)
2016
✓ Answer:CMore than 20 kHz
Ultrasound has a frequency above 20 kHz.
125
What is the approximate speed of sound in air?
RRB JE
14/12/2014
2014
✓ Answer:B330 m/s
Near 0°C, the speed is about 331 m/s, approximately 330 m/s.
126
The speed of sound increases as we increase _____.
RRB Group-D
05/10/2018 (Shift-III)
2018
✓ Answer:ATemperature
The intended answer concerns sound in air, whose speed increases with temperature. This is not a universal rule for every material.
127
What is the approximate audible frequency range for humans?
The source selects 80 dB, but the question is incorrectly worded: 80 dB is audible, not an upper hearing limit. A single universal safe exposure limit cannot be stated without duration and other conditions.
