LESSON 1 LIGHT

First Travelling of light in straight lines Activity 1 To prove that light travels in straight lines.

As a result of travelling of light in straight lines , some phenomena happen as : 1) Formation of images through narrow holes. 2) Formation of shadow.

1) Formation of images through narrow holes Activity 2 To prove that formation of images through narrow holes is due to travelling of light in straight lines.

2 -Formation of shadow: Activity 3 To prove that shadow is formed as a result of travelling of light in straight lines.

WORK SHEET • Complete the statement : • The idea of the camera depends in ………………. • The object s image that is formed through narrow hole is …………and …………… • Formation of ………………. Through narrow holes and formation of ……………… are from application of travelling light in straight lines. • Light travel in …………………. . lines. • ……………. is a darkened area that is formed when light falls on an opaque object.
