Angle is 18.66°

Explanation: When an incident light passes through two different media, the ray of light is refracted. Refraction is the bending of the light that happens when the wave changes its velocity while passing through a different surface.

The incident light makes an angle with the normal to the surface at a point. This angle is called Angle of Incidence. After going through the other medium, the wave makes a different angle with the normal. That angle is called Angle of Refraction.

Light changes velocity when passing through different media because each material has different index of refraction. For air, index of refraction is n = 1.

The incident angle, the refracted angle and index of refraction is related by the following formula, known as Snell's Law:

$n_{1}sin\theta_{1}=n_{2}sin\theta_{2}$

where

n₁ is index of refraction of the incident medium

θ₁ is angle of incidence

n₂ is index of refration of the refracted medium

θ₂ is angle of refraction

For the ray of light incident from air into a diamond, the angle of refraction is

$sin\theta_{2}=\frac{n_{1}sin\theta_{1}}{n_{2}}$

$sin\theta_{2}=\frac{1*sin70}{2.42}$

$sin\theta_{2}=0.32$

$\theta_{2}=arcsin 0.32$

$\theta_{2}=$ 18.66

The angle light makes in the diamond is 18.66°.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
