List the steps required for the physics lab.

<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

What color is the light that comes through the filter when using the flashlight?

The color of the light depends on the color of the filter. Signup and view all the answers

What color is the light that comes through the filter when using the laser pointer?

The laser pointer only produces red light, so the light that comes through the filter will be red. Signup and view all the answers

What happens when the laser pointer is used with a filter of a different color?

Little or no light comes through the filter. Signup and view all the answers

What is the purpose of using colored filters in the experiment?

Colored filters only let through light of a particular color, allowing for the observation of how different colors of light behave. Signup and view all the answers

What determines the color of a wave?

The frequency of the wave determines its color. Higher frequencies correspond to colors on the blue end of the rainbow, while lower frequencies correspond to colors on the red end. Signup and view all the answers

Why does white light appear as different colors when passing through different filters?

White light contains all colors, so when passing through a color filter, only the corresponding color of light is able to pass through. Signup and view all the answers
