Splitting Light

The video tutorial explores the nature of light and color, explaining how white light is composed of various colors. Through an experiment using a prism, it demonstrates how light is refracted and split into its constituent colors. The tutorial also covers the concept of wavelengths, showing how different colors have different wavelengths, with red having the longest and violet the shortest. It extends the discussion to the electromagnetic spectrum, highlighting that visible light is just a small part of it. Finally, it explains how broadcast quality cameras use prisms to achieve lifelike colors by splitting light into red, green, and blue wavelengths.

What is required to investigate the composition of white light?

• A light source, a screen with a slit, and a triangular glass prism

• A mirror, a flashlight, and a colored filter

• A magnifying glass, a candle, and a piece of paper

• A laser pointer, a glass of water, and a white wall

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

• It becomes brighter

• It splits into different colors

• It disappears

• It turns into a single color

Which color of light has the longest wavelength?

• Red

• Green

• Violet

• Blue

How does the direction of light change when it enters a prism?

• It splits into multiple beams

• It bends away from the base of the prism

• It remains unchanged

• It bends towards the base of the prism

What part of the electromagnetic spectrum can human eyes detect?

• Radio waves

• Visible light

• X-rays

• Gamma rays

How do broadcast quality cameras achieve lifelike colors?

• By using a black and white filter

• By capturing only red and blue wavelengths

• By splitting light into red, green, and blue wavelengths

• By using a single chip to capture all colors

What is the purpose of the three chips in broadcast quality cameras?

• To store images

• To capture different wavelengths of light

• To record sound

• To enhance brightness
