Question

Calculate the frequency of the wave shown below.

Frequency = Speed/Wavelength (λ)

Select one:
a. 4 hertz
b. 3 hertz
c. 2 hertz
d. 1 hertz

Answer 1

`\color{skyblue}{ \underline{ \frak { \: option \: ( \: c \: ) = 2 \: hertz ✓}}}`

`\: \:`

Given :

• Wavelength ( λ ) = 2 m

`\: \:`

• Speed = 4 m/s

`\: \:`

We, have to find frequency :

`\:`

• 
  `\large \tt \: Frequency = (Speed)/(Wavelength ( \: λ \: ))`

`\: \:`

• 
  `\large \tt \: Frequency = (4)/(2)`

`\: \:`

• 
  `\large \tt \: Frequency = \cancel (4)/(2)`

`\: \:`

• 
  `\pink{ \boxed{\large \tt \: Frequency =2 \: Hertz ✓}}`

`\: \:`

Hope Helps!
