Write what’s in white on the back of the Week 10 Concept Review

Then, answer the questions on the front

Your Job

Page 3: Quantum Mechanics.  Write what’s in white on the back of the Week 10 Concept Review  Then, answer the questions on the front Your Job.

Do plants need light to grow?

The quantum mechanical model developed as a result of scientists trying to explain the behavior of light

Assumed it consisted of particles Discovered light actually consists of waves

by 1900

Light

Page 5: Quantum Mechanics.  Write what’s in white on the back of the Week 10 Concept Review  Then, answer the questions on the front Your Job.

Amplitude: wave’s height from zero to the crest

Wavelength: distance between crests

Frequency: # wave cycles to pass a given point per unit of time.

The product of frequency and wavelength always equals a constant, the speed of light

Light

How are wavelength and frequency related?

QUESTION

Page 6: Quantum Mechanics.  Write what’s in white on the back of the Week 10 Concept Review  Then, answer the questions on the front Your Job.

Electromagnetic radiation includes radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays

Sunlight consists of light with a continuous range of wavelengths and frequencies. When sunlight passes through a prism, the frequencies separate into a spectrum of colors.

Electromagnetic Spectrum

QUESTION What color in the visible spectrum has the longest wavelength?

When atoms absorbs energy, electrons move into higher energy levels. These electrons then lose energy by emitting light when they return to lower energy levels.

Atomic emission spectrum: the frequencies of light emitted by an electron.

Is different for each element (like a fingerprint)

Ground State vs. Excited State Ground state; lowest possible energy an

electron can have Excited state: the level the electron jumps to.

The idea that electrons were described as waves and particles was difficult for scientists to accept.

Photon: a quantum of light; a discrete bundle of electromagnetic energy that interacts with matter similarly to particles.

Heisenberg Uncertainty principle: it’s impossible to know exactly both the velocity and the position of a particle at the same time.
