means that a body is in motion, and its velocity is measured in meters per second. And, that velocity is increasing by two meters per second, every second.

What is true about X-rays and microwaves?

erma4kov [3.2K]

I believe the correct answer from the choices listed above is option C. X-rays have greater frequency than microwaves. In a electromagnetic spectrum, the order in increasing frequency is as follows:

radio waves,microwaves, terahertz radiation, infrared radiation, visible light, ultraviolet radiation,X-rays<span> and gamma </span>rays<span>.</span>

infrared radiation from young stars can pass through the heavy dust clouds surrounding them, allowing astronomers here on earth

Mashcka [7]

The wavelength of the infrared radiation is λ = $3.174$ × $10^{-5}$ m.

<h3>What is infrared radiation?</h3>

An infrared telescope is tuned to detect infrared radiation with a frequency of 9.45 THz.

We know that,

1 THz = 10¹² Hz

So,

f = 9.45 × 10¹² Hz

We need to find the wavelength of the infrared radiation.

λ=c/f

λ = 3× $10^{8}$ /9.45× $10^{12}$

λ = 3.174 × $10^{-5}$ m

The term "infrared radiation" (IR) refers to a part of the electromagnetic radiation spectrum with wavelengths between about 700 nanometers (nm) and one millimeter (mm). Longer than visible light waves but shorter than radio waves are infrared waves.

Electromagnetic radiation with wavelengths longer than those of visible light is known as infrared, also known as infrared light. Since it is undetectable to the human eye, The typical range of wavelengths considered to be infrared (IR) is from about 1 millimeter to the nominal red edge of the visible spectrum, or about 700 nanometers.
