Question

what is the wavelength of the radiation? be sure your answer has the correct number of significant digits. 423 nm ×10⁰ part: 1 / 2 part 2 of 2 in which region of the electromagnetic spectrum is this radiation found? select the single best answer. x-ray microwave visible ultraviolet

Explanation:

Part 1: Wavelength (assuming the value is already calculated as 423 nm, no further calculation needed here as the input shows 423 nm)

The given wavelength is 423 nm. Since the problem asks for the wavelength with correct significant digits, and 423 has three significant digits, we present it as is.

The visible light region of the electromagnetic spectrum typically has wavelengths ranging from approximately 400 nm to 700 nm. The given wavelength is 423 nm, which falls within this range. X - rays have much shorter wavelengths (typically less than 10 nm), microwaves have longer wavelengths (on the order of millimeters to meters), and ultraviolet radiation has wavelengths shorter than visible light (typically 10 - 400 nm, with the visible range starting around 400 nm). So 423 nm is in the visible region.

Answer:

423 nm (or in scientific notation, if needed, it would be \( 4.23 \times 10^{2} \) nm, but based on the input, 423 nm is appropriate)
