Problem Details

A laser pointer used in a lecture hall emits light at 650 nm.

Using the figure below, predict the color associated with this wavelength.

The electromagnetic spectrum is described, ranging from low frequency at the beginning to high frequency at the end. Wavelength decreases moving from the beginning of the description toward the end. A wavelength range of 10 to the 5th to 10 to -1 represents radio frequency. A wavelength range of 10 to the -1 to 10 to the -3 represents microwaves. A wavelength of 10 to the -3 to 10 to the -6 represents infrared. A wavelength of 10 to the -6 represents the visible region. A wavelength range of 10 to the -6 to 10 to the -8 represents Ultraviolet. A wavelength range of 10 to the -8 to 10 to the -11 represents x rays. A wavelength range of 10 to the -11 and smaller represents gamma rays.
