Answer to Question #87839 in General Chemistry for mike

Question

Which of the following regions of the electromagnetic spectrum have longer wavelengths than visible light?

1. infrared radiation
2. ultraviolet radiation
3. microwave radiation


A. 2 only
B. 3 only
C. 1 and 2
D. 1 only
E. 1 and 3

Answer 1

Solution.

The wavelength range for visible radiation is 0.38-0.73 * 10 ^ -6 m. The wavelength range for microwave radiation is 1 mm. - 30 cm. The wavelength range for infrared radiation is 0.78 - 1000 * 10 ^ -6 m. The wavelength range for ultraviolet radiation is 10 - 380 * 10 ^ -9 m. So, the correct answer is infrared and microwave radiation.
