REFLECTION AND REFRACTION QUICK CHECK
What does the image of an object look like through a convex lens when the object is further from the lens than the focal point?(1 point) Responses It is upside down and smaller than the object. It is upside down and smaller than the object. It looks the same as the actual object. It looks the same as the actual object. It is upside down and larger than the object. It is upside down and larger than the object. It is right side up and larger than the object.
What happens when light rays reflect?(1 point) Responses They pass through an object. They pass through an object. They bounce back. They bounce back. They are all absorbed. They are all absorbed. They are partially absorbed.
Based on how it refracts light, what would you expect images formed by a concave lens to look like?(1 point) Responses Magnified Magnified Smaller Smaller The same as the objects that they are images of The same as the objects that they are images of Reversed
What happens to light rays when they enter a different medium?(1 point) Responses They bend. They bend. They curve. They curve. They stop. They stop. They reflect.
Use Snell’s law to determine the index of refraction of a sample of glass if a light ray that strikes the glass from air at an incident angle of 60 degrees bends to an angle of 31 degrees from the normal in the glass. (Note: Use 1.00 as the index of refraction for air.)(1 point) Responses 1.95 1.95 1.68 1.68 0.59 0.59 0.75
