Two objects, A and B, have the same momentum. If Object B has a greater velocity than Object A, then

• Object A is moving faster than Object B
• both objects have the same mass
• Object A has a smaller mass than Object B
• Object B has a smaller mass than Object A

Which of the following have shorter wavelengths and can ionize atoms, causing damage to living cells?

• infrared, visible light, x-rays
• ultraviolet light, gamma rays, x-rays
• radio, microwave, infrared
• visible light, ultraviolet light, infrared

The photoelectric effect is a phenomenon in which light, when it strikes a metal, produces photoelectrons. The photoelectric effect provides evidence to support which of the following claims?

• Metals produce electrons when exposed to light.
• Electrons can be converted into photons.
• Electromagnetic radiation such as light behaves like a particle
• Light has more energy than an electric circuit.

The image below shows different energy light sources hitting metal. Based on the photoelectric effect, what can you conclude based on the picture?

• when any frequency or intensity of light hits strikes a piece of metal, electrons are emitted
• the shorter the wavelength and higher the frequency of light, the greater the energy of the electrons emited.
• light is a particle because it can strike metal and emit particles at all colors of light
