What is the name of the type of electromagnetic radiation that has the longest wavelengths?
The table shows a set of types of electromagnetic waves and the orders of magnitude of their wavelengths.
Using the values from the table, how many wavelengths of ultraviolet radiation would have the same total length as one wavelength of infrared radiation? Answer in standard form.
Using the values from the table, how many wavelengths of the longest wavelength gamma radiation would have the same total length as one wavelength of X-ray radiation? Answer in standard form.
Which of the following could be a source of X-ray radiation?
