Flashcards in Topic 9: The Electron, Video A: Duality of Nature Deck (11):
1

Wavength:

Length of 1 full wave. Distance between 2 consecutuve troughs or peaks.

2

Amplitude:

Height of the wave as defined from the center to the top of a trough or peak.

3

When waves move through a small slit they will spread out and change. This is called?

Diffraction.

4

When waves move through a double slit they both diffract and interfere with one another. This is called?

Interference.

5

When light hits something it refracts or recoils?

It refracts.

6

When a particle hits something does it recoil or refract?

recoil.

7

Is light a wave or a particle?

Both.

8

Diffraction and interference are charactistics of waves or particles.

Waves.

9

Recoil and mass are characteristics of waves or particles.

Particle.

10

Broglie proposed that matter must have what?

A wavelength.

11

What is the Broglie equation

Lambda = h/mv. h is planck's constant which equals 6.626x10^-34. m = mass in kg. v is velocity in meters per second.
