Answer 2

Answer:

Correct Question :-

• What is the speed of a wave with a wavelength of 3 m and a frequency of 0.1 Hz ?

Given :-

• A wavelength of 3 m and a frequency of 0.1 Hz.

To Find :-

• What is the speed of a wave.

Formula Used :-

★ v = fλ ★

where,

• v = Speed of wave
• f = Frequency of wave
• λ = Wavelength

Solution :-

Given :

• Wavelength = 3 m
• Frequency = 0.1 Hz

According to the question by using the formula we get,

⇒ v = fλ

⇒ v = 0.1 × 3

➠ v = 0.3 m/s

∴ The speed of a wave is 0.3 m/s .
