Light Spectrum and Prism Activities

In this video tutorial, students explore the properties of light by using prisms to observe the visible light spectrum. The activity involves directing sunlight through a prism to separate white light into its component colors. Students work in pairs to conduct the experiment, record observations, and create a color wheel. The tutorial includes a class discussion on light refraction and color separation, emphasizing that sunlight is composed of various colors. The activity concludes with instructions for making a color wheel and a reminder to consult additional resources for further learning.

What materials are required for the activity involving the spectrum of visible light?

• Activity sheet 4, paints, cardboard, filters, and rulers

• Activity sheet 2, markers, colored paper, lenses, and glue

• Activity sheet 3, pencils, black paper, mirrors, and tape

• Activity sheet 1, crayons, white paper, prisms, and scissors

How should students hold the prism to observe the light spectrum?

• With the prism resting on a flat surface

• With both hands gripping the ends of the prism

• With their thumb and forefinger on the triangular faces, palm up

• With their palm facing down and the prism vertical

What happens to the light when the prism is rotated?

• The light remains stationary

• The light moves and stretches

• The light changes color

• The light disappears completely

Which colors are observed on the paper when light passes through the prism?

• Red, orange, yellow, green, blue, indigo, violet

• Pink, purple, brown, black, white, gray

• Cyan, magenta, yellow, black

• Gold, silver, bronze, copper

What is the correct order of colors in the visible light spectrum?

• Violet, indigo, blue, green, yellow, orange, red

• Red, orange, yellow, green, blue, indigo, violet

• Green, yellow, red, blue, violet, orange, indigo

• Blue, red, green, yellow, violet, orange, indigo

What is the term used to describe light separated into colors?

• Reflection

• Diffraction

• Spectrum

• Absorption

Why should students never look directly at the sun through the prism?

• It can cause serious eye damage

• It will make the prism opaque

• It can cause the prism to break

• It will not show any colors

What happens to white light when it passes through a prism?

• It remains unchanged

• It gets absorbed completely

• It gets reflected back

• It gets refracted and separated into colors

What is the purpose of creating a color wheel in this activity?

• To test the durability of the crayons

• To match the colors of the spectrum with the color wheel

• To create a decorative art piece

• To measure the size of the prism

Which color is not included in the color wheel but is part of the spectrum?

• Indigo

• Red

• Yellow

• Green
