Space tools

A refracting telescope uses: 

• Lens
• Mirrors
• Lens and mirrors
• Transmitters

The major problem with refracting telescopes is: 

• Using convex lens
• Creating larger images
• Distortion
• Reflection

Which is NOT a space tool? 

• Refracting telescope 
• Reflecting telescope
• Spectrascopes
• Prisms

The picture shows a picture of what telescope? 

• Reflecting
• Refracting

What are the two types of optical telescopes? 

• Reflecting/Rarefaction
• Compressional/Longitudinal
• Reflecting/Longitudinal
• Refracting/Reflecting

The telescopes that receive long wavelengths from space. 

• Space probes
• Space satellites
• Space landers
• Radio 

The best thing about radio telescopes is: 

• They can receive data any time of day and in any weather
• They can receive very high frequency signals
• They receive gamma rays
• They can intercept signals between planets 

Spectrascopes collect light and then:

• Combine them into white light
• Combine them into black light
• Separate them into bands of colors
• Seperate them into white light

Spectrascopes use bands of color to identify: 

• Mass of star
• The elements in the star
• The weight of the star
• The sounds the star makes

Which is NOT a result of using a spectrascope? 

• Determining elements in star
• Determining mass of star
• Determining temperature of a star
• Determining the age of a star.
