Electromagnetic Spectrum and Stars

All electromagnetic waves travel at 

• Speed of Sound
• the Speed of Light
• the speed of gravity
• no idea

What property of this wave is represented by the letter "A"

• amplitude

• crest

• trough

• wavelength

The highest point on a wave, letter a in picture 

• the crest
• the trough
• the top
• the coast 

The lowest point on a wave, letter b in picture is the

• Amplitude
• Crest
• Trough
• Wavelength

The number of wavelengths that pass a point each second is:

• frequency
• period
• longitudinal 
• transverse wave 

Light and other forms of Electromagnetic Radiation are given off by our sun and other stars due to 

• Nuclear Fusion
• Nuclear Fission
• Convection
• Radioactive Decay

What is red shift?

• When a star collapses.
• Galaxies and stars are moving away from us. 
• A very luminous burst of radiation
  
• When the sun collapses.

Which section of the spectrum is the ONLY one we can see?

• X-rays
• Visible Light
• Gamma Rays
• Ultraviolet Rays

Which of the following electromagnetic waves is given off as heat? 

• Radio Waves
• Infrared Rays
• Visible Light
• Gamma Rays

All electromagnetic waves have the same...

• frequency
• speed
• wavelength
• energy
