Prisma

Prisms are used to separate light into its constituent wavelengths, which is useful for analyzing the emission spectrum of stars and galaxies. Additionally, prisms are employed in optical instruments to direct light in specific directions, aiding in precise optical applications.

What is one of the primary uses of prisms in the study of celestial bodies?

• To capture images of planets

• To measure the distance to galaxies

• To separate light into its wavelengths

• To magnify distant stars

How do prisms help in analyzing the emission spectrum of stars?

• By focusing light into a single beam

• By changing the color of the light

• By amplifying the brightness of the light

• By separating light into its constituent wavelengths

In what way are prisms used in optical instruments?

• To increase the speed of light

• To direct light in specific directions

• To change the color of light

• To absorb unwanted light

What is a benefit of using prisms in optical devices?

• They simplify the design of the device

• They allow for precise light direction

• They increase the power consumption

• They reduce the size of the device

Which of the following is NOT a use of prisms in optical instruments?

• Increasing the speed of light

• Separating light into different colors

• Directing light in specific directions

• Analyzing the emission spectrum
