Problem 61

The Quantum Harmonic Oscillator

When a quantum harmonic oscillator makes a transition from the (n+1) state to thenstate and emits a 450-nm photon, what is its frequency?

Step-by-Step Solution:
Step 1 of 3

Chapter 1 PHYS 1220 SI Units  SI units are used for equations in the course o The SI unit for time is the second (s) o The SI unit for length is the meter (m) o The SI unit for mass is the kilogram (kg)  Numbers can be simplified using scientific notation  Units can be converted using a conversion factor Dimensional Analysis Density ρ=(m/v)  Dimensional analysis when the dimensions of a quantity instead of the value are used to solve a problem; this is often used to check a problem  Dimensions can be treated as algebraic symbols for example: o V=l*w*h each is a unit of length so volume is equal to L 3  The quantities can only be added or subtracted if they have the same dimensions  Each side of the equation must have the same dimensions  Trigonometric functions only apply to dimensionless quantities  Logarithms and exponential functions only apply to dimensionless quantities Significant Figures  When multiplying or dividing the answer will have the same amount of significant figures as the number in the equation with the least amount of significant figures (12.5)*(2.0)=25  When adding or subtracting the answer has the same amount of decimal places as the number with the least amount of decimal places in the problem  Numbers such as e and π don’t place restricti
