Today, astronomers know that the majority of radiation, or light, present in the universe is invisible to human eyes. By looking at the universe in all possible wavelengths, scientists are piecing together a complex picture of the unfathomably vast cosmic environment that we are a part of. It...
In the physics classroom, content based on superheroes can be used in support of learning materials on topics such as optics, advanced materials, kinematics, and the electromagnetic (EM) spectrum. Studies have highlighted several student preconceptions with regards to different radiation types. For ...
How do we see infra-red light waves?Electromagnetic Spectrum:The electromagnetic spectrum of light arranges the light waves according to their frequency and wavelength. The radio waves have the longest wavelength and used for transmission of signals while gamma rays have the least wavelength....
How are energy and frequency of electromagnetic radiation related? How does atmospheric chemistry affect the electromagnetic spectrum? How are electromagnetic waves used in communication? What is the electromagnetic radiation spectrum? How do X-rays use electromagnetic waves? How are electromagnetic ...
How does radio astronomy use the electromagnetic spectrum? How do electromagnetic waves work? Explain how the diffraction of light shows that light behaves like a wave. What is the wavelength of a fiber laser? How does the absorption of a photon of light l...
The X-ray spectrum is not to be mistaken for the X band, which is a low-energy part that is part of the electromagnetic spectrum. While both bands are separated by only a couple of hundreds of nanometers each, they do not have the same characteristics.Because X-rays are penetrating and...
TEMs are the most powerful electron microscopes: we can use them to see things just 1 nanometer in size, so they effectively magnify by a million times or more.How a transmission electron microscope (TEM) works A transmission electron microscope fires a beam of electrons through a specimen to...
They repeat this process for every filter they may use in the final composite image. Next, our imaging specialists upscale longer wavelength images so they match the higher resolution of shorter wavelength images. And, yes, it is possible to do this while maintaining the overall image quality!
Electromagnetic (EM) radiation, on the other hand, has no mass and travels in waves. EM radiation can range from very low energy to very high energy, and we call this span the electromagnetic spectrum. Within the EM spectrum, there are two types of radiation -- ionizing and non-ionizing....
You may have already guessed a couple of problems that we'll have to solve. First, what do we do when the sun isn't shining? Solving Solar Energy Issues If you worry that your solar cells won't perform on a stormy day, you can always store the sun's energy in backup batteries. ...
