Answer:
Angle of reflection = 30°
Explanation:
One of the laws of reflection is that the angle of incidence is equal to the angle of reflection.
The angle at which the light strikes the mirror is called the angle of incidence while the angle at which the light gets reflected back is called angle of reflection.
In this case, the angle of incidence is 30 degrees. So, we can say that the angle of reflection is also equal to 30 degrees.
The metric unit is the Newton (N), or the
Total internal reflection occurs when a propagated wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface. <span>Total internal reflection can be observed while swimming, when one opens one's eyes just under the water's surface. If the water is calm, its surface appears mirror-like.</span>
We have no idea what the 1.5 means. Fortunately, we don't need it.
Resistance = voltage / current
= (89 v) / (8 A) = 11.125 ohms
