Question: X-rays have a wavelength smail enough to image individual atoms, but are challenging to detect because of their typical frequency. Being more energetic than visible light, X-rays are able to penetrate soft tissues but not bones, and so allow us to make images of Within this visible range our eyes perceive radiation of different wavelengths (or frequencies) as light of different colors, ranging from red to violet in order of decreasing wavelength. [8], Infrared waves are larger than the visible spectrum and smaller than microwaves. $$mc=\frac h\lambda$$ Wavelength of X-rays Fortunately, many objects, such as stars, are very close to being blackbodies and behave approximately as a blackbody would, which allows scientists to use the concept of blackbodies in their studies. ; that is, they repeat regularly in both space and time. Multi-wavelength data analysis of ONC X-ray sources. A blackbody curve is a theoretical construct of the total amount of radiation an object emits. where $h$ is Planck's constant, $e$ is the charge of the electron, and $c$ is the speed of light.
