Question

the formula for calculating the speed of light (3.00 x 10^8ms^-1) is
○ c = λ/v
○ c = λ x v
○ λ = c x v
○ v = λ/c

Explanation:

The speed of light \(c\) is related to wavelength \(\lambda\) and frequency \(v\) by the formula \(c=\lambda\times v\). This is a fundamental formula in wave - related physics (specifically for electromagnetic waves like light).

Answer:

B. \(c = \lambda\times v\)
