Spectrum

The video explains how white light is refracted through a prism, creating a spectrum. It discusses the electromagnetic spectrum, which extends beyond visible light, including radio waves and gamma radiation. The term 'spectrum' is also used in other contexts, such as ionic mass and audio frequencies.

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

• It is dispersed into different colors.

• It is reflected back.

• It remains unchanged.

• It is absorbed completely.

Which of the following is NOT part of the electromagnetic spectrum?

• Sound waves

• Visible light

• Gamma radiation

• Radio waves

What is the range of the electromagnetic spectrum?

• From infrared to ultraviolet

• From low-frequency radio waves to high-energy gamma radiation

• From microwaves to X-rays

• From visible light to infrared

In what context might the term 'spectrum' be used outside of light?

• To measure the speed of sound

• To refer to ionic mass in a mass spectrum

• To calculate the distance of stars

• To describe the range of colors in a rainbow

Which of the following is an example of a spectrum in audio frequencies?

• The range of colors in a painting

• The speed range of a vehicle

• The pitch range of a musical instrument

• The temperature range of a climate
