Formulas and conversions

Question 0

Energy of a photon

Answer 0

Energy of a photon equals Planks constant times frequency

Ε=hν

Question 1

Frequency and wavelength

Answer 1

Speed of light equals wavelength times frequency

c=λν

Question 2

Change in energy

Answer 2

Change in energy equals Planks constant times speed of light times Rydbergs constant times the difference of 1/final quantum number squared minus 1/initial quantum number squared
Δ=hcR_H((1/nf^2)-(1/ni^2))

Question 3

1 Angstrom

Answer 3

One angstrom equals ten raised to the power of negative ten meters
1Å=10^(-10)m

Question 4

Momentum

Answer 4

Wavelength equals Planks constant devided by the product of mass times velocity, with mass times velocity equaling momentum

λ=(h)/(m•v)

Question 5

One joule

Answer 5

One joule is equal to one kilogram multiplied by the quotient of meters squared divided by seconds squared

1J=1kg•((m^2)/(s^2))
