10 Questions
According to the photoelectric effect, which of the following statements is true?
Greater frequency of light results in greater energy of electrons.
What did Einstein propose in 1905 about light?
Light is made up of particles called photons.
What is the relationship between a photon's energy and its frequency?
The energy of a photon is directly proportional to its frequency.
What is the value of Plank's constant?
6.63 x 10-34 Js
Why does brighter light result in more electrons being ejected?
Brighter light has a greater number of photons.
Which experiment did Rutherford conduct to study the structure of the atom?
The gold foil experiment
What did Rutherford observe when he shot alpha particles at a thin sheet of gold foil?
Most alpha particles went straight through the gold foil
What is the nuclear model of the atom proposed by Rutherford?
Most of the mass is concentrated in the nucleus
What is the problem with the nuclear model of the atom proposed by Rutherford?
The electrons aren't going straight to the positively charged nucleus
Why would orbiting electrons in the nuclear model slow down and be pulled into the nucleus?
Because moving charged particles emit electromagnetic radiation
