- An electron, traveling at a speed of 9.00 x 107 m/s, strikes the target of an X-ray tube. Upon impact, the electron decelerates to one-quarter of its original speed, an X-ray photon being emitted in the process. What is the wavelength of the photon? 2.67 x 10-11 m 3.76 x 10-11 m 2.88 x 10-11 m 5.34 x 10-11 m 5.75 x 10-11 mHow many photons per second are emitted by the antenna of a microwave oven if its power output is 1 kW at a frequency of 2560 MHz? photons/sA photon of wavelength 200 nm is scattered by an electron that is initially at rest.

- Your answer is partially correct. A spectral emission line is electromagnetic radiation that is emitted in a wavelength range narrow enough to be taken as a single wavelength. One such emission line that is important in astronomy has a wavelength of 21 cm. What is the photon energy in the electromagnetic wave at that wavelength? Number 9.465714286 Units eVThis question relates to the practicality of searching for intelligent life in other solar systems by detecting their radio broadcasts (or aliens find us from ours). The closest stars are 4 light years away from us. How far away must you be from a 460 kHz radio station with power 50.0 kW for there to be only one photon per second per square meter? Assume that the photons spread out spherically. The area of a sphere is 4??24πr2. b) How many lightyears away is this?The diameter of an atomic nucleus is about 10 × 10-¹5 m.
