What can a diffraction grating be used for?
measuring wavelengths of light
How is the refractive index used?
The refractive index measures the speed of light and wavelengths. Measuring the refractive index of an object by wavelengths is very confusing to most people. Many scientists have got it figured out.
How are wavelengths of light detected?
Spectroscopy originated through the study of visible light dispersed by a prism according to its wavelength. An instrument called a spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities.
How is sound projected?
The directivity (narrowness) of all wave producing sources depends on the size of the source, compared to the wavelengths it generates. Audible sound has wavelengths ranging from a few inches to several feet, and because these wavelengths are comparable to the size of most loudspeakers, sound generally propagates omnidirectionally. Only by creating a sound source much larger than the wavelengths it produces can a narrow beam be created. In the past, loudspeaker manufacturers have created large speaker panels or used reflective domes to provide some directivity but, due to the sound's large wavelengths, the directivity of these devices is still extremely weak.
How does the electromagnetic spectrum arrange different types of radiation?
Yes. The different types are determined by their wavelength. We have assigned 7 commonly-used names to the different wavelengths (although within each type, you can get more wavelengths, as it is a continuous scale). The names are, from long wavelengths to short: Radio Waves, Microwaves, Infrared, Visible Light (the one we can see with our eyes), Ultraviolet, X-rays, and Gamma Ways (γ-rays). Ultraviolet, X-rays and gamma rays are ionizing, which means they can add or remove electrons from atoms, which can change the way they react. This is why they are dangerous. Infrared, microwaves and radio waves are not ionizing. They have longer wavelengths and less energy. Radio waves can have wavelengths of hundreds of meters, and visible light has wavelengths on the order of nanometers.
