- How do light rays behave on flate convex and concave mirrors
Flat – the light ray reflects back at the same angle
Convex – The light rays bounce inwards or get wide
Concave – The light ray bounces outwards or spreads out
Mirrors – The light ray spreads out from the source in all directions and when striking a mirror they are reflected at an angle at which the light arrives
What is Reflection – Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns to the medium from which it originated. Common examples include the reflection of light, sound, and water waves.
What is Refraction – the bending of a ray when it passes at an angle from one medium into another in which its speed is different (as when light passes from air into water)
How do different mediums change refraction – If light enters any substance with a higher refractive index (such as from air into glass) it slows down. The light bends towards the normal line. If light travels enter into a substance with a lower refractive index (such as from water into the air) it speeds up. The light bends away from the normal line
