List down at least 5 scientists who conducted experiments about how electrons

behave like waves. Give their correct last names.

According to the wave equation, what is the relationship between the frequency

and wavelength of light?

"Refraction" of light occurs when ________.

• light bounces off a surface.

• light bends around corners or obstacles.

• light changes direction due to a change in speed.

• light waves add together to make a new wave with larger amplitude.

"Diffraction" of light occurs when ________.

• light bounces off a surface.

• light bends around corners or obstacles.

• light changes intensity when passing from one material into another.

• light waves add together to make a wave with larger amplitude.

For diffraction of a wave to occur,

• the wave must be a sound wave.

• the wave must be traveling from a less dense to a denser material.

• the wave must be traveling slower than the speed of light in a vacuum.

• the wave must encounter an obstacle that is comparable in size to the

  wavelength of the wave.

"Constructive" and "destructive" interference refer to the phenomenon of

______.

• waves adding together or canceling each other out when they are

  superimposed.

• waves traveling different distances.

• waves bending around obstacles.

• waves changing direction when moving from one material to another.

Which of the following shows destructive interference of light?

• 
• 
• 
• 

Which of the following would possibly happen at daytime if there were no

particles and no scattering of light in the atmosphere?

• blue sky

• black sky

• white clouds

• red subset
