Question 1.
What is the formula to calculate wave speed?
Show hintHide hint
Think about the basic relationship between distance and time.
Question 2.
If the tension of a string is increased, what happens to wave speed?
Show hintHide hint
Consider how tension affects restoring forces.
3Question 3.
What is the relationship between wave speed, frequency, and wavelength?
- v = λν
- v = νλ
- both are correct
Show hintHide hint
Consider the principles of wave propagation.
4Question 4.
In a stretched string, how does increasing the tension affect the wave speed?
- True
- False
Show hintHide hint
Reflect on how tension affects motion in physics.
Question 5.
Consider a wave traveling along a string with a tension of 120 N and linear mass density of 0.25 kg/m. Calculate the wave speed.
Show hintHide hint
Use the wave speed formula directly.
Question 6.
A sound wave travels in a gas at a temperature of 20°C where the density is 1.2 kg/m³ and the bulk modulus is 1.4 x 10^5 Pa. Find the speed of sound.
