Describe the relationship between the frequency, wavelength, and velocity (speed) of a wave. - AnswerThe 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 any one (frequency, wavelength, or velocity) given the...

What is the peak called on mass spec? correct answersMolecular ion How do you calculate relative atomic mass? correct answers(mass no x abundance%) + (mass no x abundance%) / 100 What is nuclear fusion? correct answersWhen 2 light atomic nuclei fuse together to form a heavier nucleus of a new element. What did John Dalton discover? correct answersFound atoms are solid spheres made of tiny particles. What did J.J Thompson discover? correct answersThe plum pudding model: ball of positi...

Why are alpha particles deflected by the nucleus? - Answer-Because both the alpha particles and the nucleus are positively charged and so the alpha particle is repelled. Is this statement (Dalton's Theory) true or false and why? "All atoms of an element are identical and have the same mass and properties." - Answer-False. Atoms of the same element can have different numbers of neutrons. What is the evidence that electrons are subatomic particles? - Answer-The nature of the electron is i...
