Speed of Waves Required Practical

What is the definition of speed of waves?

• The distance traveled by a wave per unit time.

• The frequency of a wave.

• The amplitude of a wave.

• The time taken for a wave to travel a certain distance.

How is the speed of waves calculated?

• Frequency multiplied by wavelength

• Amplitude divided by wavelength

• Distance divided by time

• Time divided by distance

What is the unit of measurement for speed of waves?

• miles per hour

• kilometers per hour

• feet per second

• meters per second

What are the two factors that affect the speed of waves?

• amplitude and velocity

• temperature and pressure

• medium and direction

• wavelength and frequency

What is the formula to calculate the speed of waves?

• v = fλ

• v = f + λ

• v = f/λ

• v = λf

What is the speed of sound in air?

• 123 meters per second

• 500 meters per second

• 343 meters per second

• 1000 meters per second

What is the speed of light in a vacuum?

• 299,792,458 meters per second

• 400,000,000 meters per second

• 200,000,000 meters per second

• 300,000,000 meters per second

How does the speed of waves change when traveling from one medium to another?

• The speed of waves always increases when traveling from one medium to another.

• The speed of waves can either increase or decrease when traveling from one medium to another.

• The speed of waves remains constant when traveling from one medium to another.

• The speed of waves always decreases when traveling from one medium to another.
