1.1 Electromagnetic Radiation and Atom Spectra

Question 1

C =Fh

Answer 1

C=Speed of light, F=Frequency, H(lamda)=Wavelength

Question 2

The wavelength of visible light is expressed in

Answer 2

Nanometers

Question 3

A photon carries

Answer 3

a quantum of energy

Question 4

In emission spectroscopy higher temps are used to

Answer 4

excite electrons within the atom and as electrons drop to lower energy levels photos are emitted

Question 5

As frequency increases

Answer 5

Wavelength decreases

Question 6

Grannys eX Used to Vist In Melrose Regularly

Answer 6

Gamma rays, X-rays,Ultraviolet,Visible,Infrared,Microwaves, Radiowaves

Question 7

Visible light is between

Answer 7

Infrared and ultraviolet (400nm-700nm)

Question 8

E=hf

Answer 8

Where H is Planck’s constant

Question 9

E=Lhf

Answer 9

Avogadro’s constant and only use L if it’s in moles

Question 10

How is a line produced in an emission spectrum?

Answer 10

The excited electrons moves up to a higher energy level and then drops back down to a lower energy level. This releases a photon of energy which correspond to a specific wavelength

Question 11

What do different line mean?

Answer 11

There are multiple electron transitions
