Unit 5/6 Review EC: Wave Calculations & Orbital Notation

Match the following

• Energy Unit

• m/s

• Plank´s Constant Unit

• J

• Speed of Light Unit

• m

• Frequency Unit

• Hz or 1/s

• Wavelength Unit

• J*s

Match the following

• Energy Symbol

• E

• Plank´s Constant Symbol

• c

• Wavelength Symbol

• λ

• Speed of Light Symbol

• f

• Frequency Symbol

• h

Organize these options under the equation you would use to solve them.

Groups:

(a) c = λ*f

,

(b) E = h*f

,

(c) E = h*c/λ

• have E but need λ

• have λ but need E

• have f but need E

• have E but need f

• have λ but need f

• have f but need λ

Organize these problems under when you would get each symbol in the equation alone.

Groups:

(a) need to get λ alone

,

(b) need to get E alone

,

(c) need to get f alone

• have f but need λ

• have λ but need E

• have λ but need f

• have E but need f

• have E but need λ

• have f but need E
