Question

State True or False: "Wavelength of red light is close to \( 700 \text{ nm} \)."

Hint:

The visible spectrum of light ranges from violet (~400 nm) to red (~700 nm). Red light specifically has wavelengths close to 700 nm, typically ranging between 620 nm and 750 nm.

Answer 1

The wavelength of red light is typically in the range of \( 620 \text{ nm} \) to \( 750 \text{ nm} \). The value \( 700 \text{ nm} \) is a commonly accepted wavelength for red light in the visible spectrum, so the statement is true.
