Chem 141 exam 2 MSU Questions and Answers 100% Pass Describe the relationship between the frequency, wavelength, and velocity (speed) of a wave. The more times the wave is passing through a point in space = a higher frequency, the higher frequency creates a smaller wavelength, which is why the smallest wave is a gamma wave, it has the highest frequency and the shortest distance between waves, the velocity can be measured in m/s and is composed of frequency and wavelength Calculate a...

Radiation - ANS energy in transit from one location to another; a transfer of energy that results from either a change occurring naturally within an atom or a process caused by the interaction of a particle with an atom Ionizing Radiation - ANS radiation that produces positively and negatively charged particles (ions) when passing through matter Attenuation - ANS any process that decreases the intensity of the primary photon beam directed toward some destination; total reduction i...

AQA AS LEVEL PHYSICS 7407/1 Paper 1 Mark Scheme June 2022. An electron in the beam collides with an electron in the gas particle. OR An electron in the beam transfers (some of its kinetic) energy to an electron in the gas particle  One (atomic) electron leaves the gas particle MP1 is awarded for the description of the electron-electron interaction or the resulting energy transfer between these electrons. Treat the gas particles are ‘excited’ as neutral, must mention an inter...
