Question

solving for cos theta

Answer 1

\[\Delta \lambda = h/mc (1-\cos \theta) \]

Answer 2

so for change in wavelength i got 1.2x 10 ^ -12

h is planks constant =6.63x 10^-34
m is 9.11 x10^-31 kg
c is the speed of light



so i got these values so how would you find cos theta with that equation?

Answer 3

Answer 4

cross multiplication to get cos theta upside
\[- \cos \theta = \frac{ h }{ mc \Delta \lambda } -1\]
then divide by -1 and take inverse cos
