Answer #1

ANSWERS: Option A, Option D and Option E

Explaination:

Electromagnetic Radiation is created by Accelerated charged particles. Neutron moving in circle will have centripetal acceleration but it is not charged, so it cannot generate EM radiation.

Speeding proton means the proton has acceleration. Hence, it will produce EM radiation.

An electron bouncing up and down will create oscillating electric and magnetic fields and hence will generate EM radiations. Hence, Option D.

An electron moving in circle will have Centripetal acceleration and accelerated charged particles produce Em radiations. Hence, Option E.

An electron, a neutron(which has zero charge) and a proton are in an electric field generated by charged plates which points in the +x direction. The three particles are sufficiently far apart that their forces on each other are negligible. Assume also that forces other than the electrostatic ones on the three particles are negligible. We know that: (Choose the correct answers) the acceleration of the electron is in the +x direction. the x coordinate of the electron is less...

The diffraction of radiation can be used to determine the spacing between atoms. In practice, the wavelength of the radiation used should be restricted to a value which is of the same order of magnitude as the interatomic distances to be determined. Such experiments are commonly performed using X-rays (electromagnetic radiation), however a beam of subatomic particles, such as of neutrons or electrons, may also be used if their corresponding de Broglie wavelength is of the appropriate magnitude. Calculate the...

(a) Galaxies emit electromagnetic radiation from the transition of electrons between different atomic orbits in hydrogen. One such transition is called the Lyman-α transition. When this transition occurs in hydrogen in the lab it produces light with wavelength λemit = 121.567 nm. This transition has been observed in one of the most distant objects ever seen, called a quasar. The observed wavelength of the Lyman-α transition from the quasar is λobs = 866.0 nm. What is the redshift of the...

Quarks and gluons are fundamental particles that will be discussed in Chapter 44. A proton, which is a bound state of two up quarks and a down quark, has a rest mass of mp=1.67×10−27 kg.mp=1.67×10−27 kg. This is significantly greater than the sum of the rest mass of the up quarks, which is mu=4.12×10−30 kgmu=4.12×10−30 kg each, and the rest mass of the down quark, which is md=8.59×10−30 kg.md=8.59×10−30 kg. Suppose we (incorrectly) model the rest energy of the proton...

I discussed the idea of hooking up a video camera to a visible-light microscope and recording the trajectory of an electron orbiting a nucleus. An electron in an atom typically has a speed of about 1% of the speed of light. (a) Calculate the momentum of the electron. (b) When we make images with photons, we can't resolve details that are smaller than the photons' wavelength. Suppose we wanted to map out the trajectory of the electron with an accuracy...
