6. Spectroscope                   f. Uses a chemical accumulation of light

7. Radio Telescope              g.Separates light from stars into the color spectrum                              

8. Inverted                           h. Antenna and receiver

To Do:

Match the columns

Solution:

What is an aberration?

• When the focal lengths of a lens are not equal, some deviation of light occurs, causing the image to be formed to be blurry.
• Hence, aberration(1) corresponds to option d. Fuzzy Image.

How does a camera work?

• A camera accumulates all the light around it from different directions and focuses it at a singular point to get a sharp image.
• Thus, 2 corresponds with f. Uses a chemical accumulation of light.

What is refraction?

• Refraction is the bending of light when it passes from one medium to another.
• Hence 3 corresponds with c. Bending of light.

What is an objective lens?

• A telescope/microscope consists of 2 convex lenses- the objective and the eyepiece.
• Thus 4 corresponds with a. Large, transparent glass.

Mirror

• A mirror consists of a refractive material like glass, which is silvered on one side. It reflects light.
• Hence 5 corresponds with option b. Collects and reflects light.

What is a spectroscope?

• A spectroscope is a device that measures parameters of the spectrum of light. It works by splitting light into its different wavelengths.
• Thus, 6 corresponds with g. Separates light from the stars into the component color spectrum.

How does a radio telescope work?

• A radio telescope is a large device. It has a specialized antenna and receiver to transmit and receive signals from astronomical objects.
• Thus, 7 corresponds with option h. Antenna and receiver.

What does inverted mean?

• Inverted means upside down.
• So option 8 corresponds with option e. Upside Down.

Therefore, the correct answers are:

1. Aberration-Fuzzy Image

2. Camera - uses a chemical accumulation of light

3. Refraction-bending of light

4. Objective Lens- large transparent glass

5. Mirror- collects and reflects light

6. Spectroscope- Separates light from stars into the component color spectrum

7. Radio Telescope- Antenna and receiver

8. Inverted- upside down
