Flashcards in Topic 8: Spectroscopy, Video D: Photons Deck (14):
1

What is the equation for the energy of light?

= hv = hc/lambda

2

What is Planck's constant?

6.626 x 10-34J-s

3

Frequency is measured in what unit?

s-1

4

Wavelength is measured in what unit?

Meters.

5

Does red light have enough energy to overcome the bonding of electrons and kick them out?

No.

6

Does blue light have enough energy to overcome the bonding of electrons and kick them out? 

Yes because it has a higher frequency.

7

Light is made up of particles called what?

Photons. Photons have frequencies.

8

Higher frequency radiation has higher what?

Energy.

9

Lower frequency radiation has lower what?

Lower energy.

10

Shortwavelength has high what? Give examples.

Energy and frequency.

(X Ray, Gamma Ray, Ultraviolet)

11

Long wavelength has low what? Give examples.

Low energy and frequency.

(Radio, Microwave, Infrared/Fire)

12

True or false. The wavelength and energy of a photon are inversely proportionally.

True

13
