Frequency

Question 18

3x10^8 m/s or c

Answer 18

Speed of light

Question 19

C = (lambda)f

Answer 19

C-> speed of light
F-> frequency
Lambda -> Wavelength

Question 20

E= (h)f

Answer 20

E-> energy
H-> Planck’s constant
F-> frequency

Question 21

E=h c/lambda

Answer 21

Energy = Planck’s constant x speed of light divided by the wavelength

Question 22

Formula for lambda

Answer 22

Lambda = constant speed of light divided by frequency

Question 23

Formulas for frequency

Answer 23

Frequency= speed of light divided by lambda

F= energy divided by Planck’s constant
