Question

The following are representative wavelength in the infrared, ultraviolet, and x-ray regions of the electromagnetic spectrum, respectively: 1.0*10⁻⁸m and 1.0*10⁻¹⁰m. What is the wavelength in the infrared region?

1) 1.0*10⁻⁸m
2) 1.0*10⁻¹⁰m
3) Cannot be determined

Answer 1

The infrared wavelength among the given options is 1.0*10⁻⁸m, as it falls into the infrared range of the electromagnetic spectrum.

The correct option is 1.

Step-by-step explanation:

The student asked what the wavelength in the infrared region is, given the wavelengths 1.0*10⁻⁸m and 1.0*10⁻¹⁰m which represent regions in the electromagnetic spectrum. To answer this question, we refer to our knowledge of the electromagnetic spectrum, where infrared wavelengths range from about 1.0*10⁻⁶m to 1.0*10⁻³m.

Given the options, 1.0*10⁻⁸m and 1.0*10⁻¹⁰m, the wavelength 1.0*10⁻⁸m falls within the range of ultraviolet (UV) radiation, and 1.0*10⁻¹⁰m falls in the range of X-rays. Therefore, we can determine that the correct answer is option 1) 1.0*10⁻⁸m for the infrared wavelength.

The correct option is 1.
