The anode (positive terminal) of an X-ray tube is at a potential of 120,000 V with respect to the cathode (negative terminal). How much work (in Joules) is done by the electric force when an electron is accelerated from the anode to the cathode? If the electron is initially at rest, find the speed of the electron when it arrives at the cathode. (e = 1.6 * 10^-19 C, me =9.1 * 10^-31 kg)

In an X-ray tube, a uniform electric field E extends over a distance of 12 cm from an electron source to a target; the field points from the target to the source. If the potential difference between the source and target is 40 kV then what is the magnitude of the electric field? What is the energy gained by an electron as it accelerates from source to target? Express the energy both in electronvolts and joules.

How do you do these? Please show step by step Properties of Waves - Copy Learning Goal: To understand electromagnetic radiation and be able to perform calculations involving wavelength, frequency, and energy. Several properties are used to define waves. Every wave has a wavelength, which is the distance from peak to peak or trough to trough. Wavelength, typically given the symbol λ(lowercase Greek "lambda"), is usually measured in meters. Every wave also has afrequency, which is the number of wavelengths...
