<ol> <li>Empty the tissue box and cover the tissue opening with a cloth. 2. Cut a hole in one of the small ends of the tissue box. 3. Cover the hole with a colored filter. 4. Place the flashlight inside the box and point it at the filter-covered opening. 5. In a dark room, point the opening at a white surface and observe the appearance of the light. 6. Repeat the process with a laser pointer. 7. Replace the colored filter with a different color and repeat the experiment. 8. Note down observations.</li> </ol> Signup and view all the answers
