question 39

Multiple Choice

Solve the problem.
-Snell's Law states that $\frac { c _ { 1 } } { c _ { 2 } } = \frac { \sin \theta _ { 1 } } { \sin \theta _ { 2 } }$ . Use this law to find the requested value. If $c _ { 1 } = 6 \times 10 ^ { 8 }$ , $c _ { 2 } = 4.66 \times 10 ^ { 8 } , \theta _ { 1 } = 43 ^ { \circ }$ , find $\theta _ { 2 }$ . Round your answer to the nearest degree.

• A) \(\theta _ { 2 } = 31 ^ { \circ }\)
• B) \(\theta _ { 2 } = 34 ^ { \circ }\)
• C) \(\theta _ { 2 } = 32 ^ { \circ }\)
• D) \(\theta _ { 2 } = 35 ^ { \circ }\)

Definitions:

K+

Potassium ion, an essential electrolyte involved in various body functions including nerve signal transmission and muscle contraction.

Hyperpolarize

A change in a cell's membrane potential that makes it more negative, moving it further away from initiating an action potential.

Hyperpolarization

An increase in a cell's membrane potential, making the interior of the cell more negative and less likely to fire an action potential.

Plasma Membrane

The semipermeable membrane surrounding the cytoplasm of a cell, responsible for controlling the passage of substances in and out.
