Part B. Two of the types of infrared light, IR-C and IR-A, are both components of sunlight. Their wavelengths range from 3000 to 1,000,000 nm for IR-C and from 700 to 1400 nm for IR-A. Compare the energy of microwaves, IR-C, and IR-A.
Rank from greatest to least energy per photon. To rank items as equivalent, overlap them.
Electromagnetic radiation behaves both as particles (called photons) and as waves. Wavelength (λ) and frequency (ν) are related according to the equation:
where c is the speed of light (3.00 × 108 m/s). The energy (E in joules) contained in one quantum of electromagnetic radiation is described by the equation:
where h is Planck's constant (6.626 × 10−34 J•s). Note that frequency has units of inverse seconds (s−1), which are more commonly expressed as hertz (Hz).
