16. The words that we should say more often!!

17. Light for seeing Light rays travel at a very high speed in straight lines from a light source and go into our eyes. Note: Light rays radiate outward from a light source and enter our eyes. The light enters our eyes through a small hole in the center called the pupil.  Note: The opening in the center of our eye, known as the pupil, allows the light to enter. 17

18. Light Paths But how do we see objects that are not light sources? To understand this, we can use ray diagrams. Note: Light travels from the light source, reflects off the object, and finally reaches our eyes. It is essential to draw the arrow in the correct direction when creating ray diagrams. 18
