Question

encountered infrared waves! ... see infrared waves, but they are all around us. the unique characteristics of infrared waves have led to their use in tv remote controls, thermal imaging cameras, and devices that monitor earth and space. this model shows different types of electromagnetic waves. the electromagnetic spectrum chart of electromagnetic spectrum with visible light, wavelength, frequency complete the sentence. compared to visible light, infrared waves have dropdown wavelengths, have dropdown frequencies, and carry dropdown energy.

Explanation:

• Wavelength: From the electromagnetic spectrum diagram, infrared waves are to the left of visible light. On the wavelength axis (units in meters), values increase to the left. So infrared has longer wavelengths than visible light.
• Frequency: Frequency and wavelength are inversely related ($c = \lambda f$, where $c$ is the speed of light, $\lambda$ is wavelength, and $f$ is frequency). Since infrared has longer wavelengths, it has lower frequencies.
• Energy: The energy of a photon is given by $E=hf$ (where $h$ is Planck's constant and $f$ is frequency). Lower - frequency infrared waves carry less energy than visible - light waves.

Answer:

longer wavelengths, have lower frequencies, and carry less energy.
