Question

In the following, which is the wavelength? v = 640 x 10³ s⁻¹; λ = 470 m

A. 3.00 x 10⁻⁸ m/s
B. 640 x 10³ s⁻¹
C. 470 m
D. 1.36 x 10³/s

Answer 1

The correct answer for the wavelength in the question provided is understood as 470 m, but due to a typographical error, it should most likely be 470 nm.

Step-by-step explanation:

The wavelength in the given question is denoted by λ, which stands for wavelength. The correct answer to the question, 'which is the wavelength?' is option B. 470 mA. However, this appears to be a typographical error as 'mA' denotes milliAmperes, which is a unit of electric current, not of wavelength. The correct unit should likely be 'nm' (nanometers) or some other unit of length. Assuming it to be a typo, the wavelength would then be correctly described as 470 m if 'mA' was intended to be 'm', or more plausibly, 470 nm (nanometers) if this represents a common wavelength unit for light.
