__________ lenses refract light rays in toward a central point. When this lens is held close to your eye, the image is magnified and right side up.
convex
Cassie's observation is due to light refraction. The light rays are bent when they travel through the water and the glass.
at the north and south pole
If the prey is moving toward the bat, the waves will be very close together.
6 J
The balloon gains a negative charge through friction.
infrared
Energy cannot be created or destroyed.
Where does a bar magnet have the strongest magnetic force?
