on a boundary with corn oil. What is the angle of refraction, to the nearest degree, for this
light ray in the corn oil?
The angle of refraction of light ray in the corn oil is 20°.
Angle of refraction is the angle the refracted light ray makes with the normal to the oil-air interface.
Given data:
Angle of incidence = 30°
Analysis:
The refractive index of oil is 1.47.
Using the formula for refractive index(n) =
1.47 =
1.47(sin r) = sin 30
sin r =
sin r = 0.3401
r = arc sin(0.3401)
r = 19.88° which is approximately 20°

Answer:
its 20 degrese
Explanation:
The correct answer is B. Although it is unknown who invented the microscope, Sir Isaac newton developed calculus along with Gottfried Leibniz. Sir Isaac Newton is also known for his three laws of motion. Newtons discoveries and theory set the stage for many other advancement in astronomy.

The force of inertia is the property common to all bodies that remain in their state, either at rest or in motion, unless some external cause is introduced to make them alter this state.
