Question

What is the speed of a wave with a wavelength of 3 m and a frequency of .1 Hz? 0.03 m/s 0.3 m/s 3.1 m/s 30 m/s

Answer 1

Answer:

The correct answer is option b, 0.3m/s

Step by Step solution:

The relation between speed, wavelength and frequency of a wave is given by the following equation:  

Speed = Wavelength x Frequency

Substituting the values in above equation we get –  

= 3  x 0.1  

= 0.3 m/s  

Answer 2

The speed of the wave with a wavelength of 3 m and a frequency of 0.1 Hz is 0.3 m/s

Velocity of a wave

The velocity of a wave is related to its frequency and wavelength according to the following equation:

Velocity (v) = wavelength (λ) × frequency (f)

v = λf

How to determine the speed of the wave

• Wavelength (λ) = 3 m
• Frequency (f) = 0.1 Hz

• Velocity (v) =?

v = λf

v = 3 × 0.1

v = 0.3 m/s

Thus, the speed of the wave is 0.3 m/s
