Electromagnetic Radiation Can Be Specified by Its Wavelength (λ), Its

Multiple Choice

Electromagnetic radiation can be specified by its wavelength (λ) , its frequency (υ) or its period (τ) . The period τ is the time it takes one complete wavelength to pass a point in space. Based on this information, what is the mathematical relationship between υ and τ?

A) υ = 1/τ
B) υ= τ
C) τ = υ/ с
D) с = τ × υ
E) τ = с/υ
