3 cards from this section. Quick, good the night before a test.
What are Newton's Rings?
Think about the formation due to light waves.
What does the symbol 'n' represent in the formula for dark rings?
It’s a counting number!
What causes the formation of Newton's Rings?
Think about how waves interact.
True or False: The radius of dark rings increases with an increase in wavelength.
Use the formula as a reference.
If an experiment using light of wavelength 700 nm generates a 4th dark ring with a radius of 0.02 m, what is the radius of curvature of the lens used?
Identify all variables accurately and apply the correct formula.
A lens creates Newton's Rings showing 8 dark rings. If the wavelength is increased to 800 nm, how many dark rings can be expected to shift higher?
Assess the effect of wavelength on quantity of observed rings.
