Question

2. A wave with a frequency of 12 Hz is travelling at a speed of 98 mis. What is the
wavelength ?​

Answer 1

Answer :-

• Frequency of wave = 12 Hz
• Speed of wave = 98 m/s
• Wavelength = ?

Here we need to find the wavelength (λ). To calculate wavelength we will use the given below formula :

↠ V = nλ

Here,

• V = speed of wave
• n = frequency of wave
• λ = Wavelength

Rearranging the above formula we have :

↠ λ = V/n

↠ λ = 98/12

Dividing Numerator as well as denominator by 2 we have :

↠ λ = 49/6

↠ λ = 8.17 m
