The formula f equals c over lambda, where f = frequency, c = wave speed, and λ = wavelength, is used to calculate frequency. Solve this formula for c.

A.c = f − λ
B.c = fλ
C.c = f + λ
D.c equals f over lambda

Respuesta :

Step-by-step explanation:

if f = c/lambda

then c = f × lambda

Answer:

B. c = fλ

Step-by-step explanation:

Given formula,

f equals c over lambda,

[tex]\implies f=\frac{c}{ \lambda}[/tex]

Where, f = frequency,

c = wave speed,

λ = wavelength,

By the above formula,

[tex]f\times \lambda = c[/tex]   ( By cross multiplication ),

Hence, the required formula for c,

[tex]c=f\lambda[/tex]

Option 'B' is correct.
