ELO 3 and 4 Space Exploration Review

An apparent shift in the position of an object when viewed from different locations. 

• Parallax
• Perihelion
• Solar Nebula
• Prominence

A good way to practice parallax is with your

• Foot

• Toes

• Thumb

• Head

With greater distance, the parallax angle

• increases

• decreases

• stays the same

Spectrum

• a band of colors, as seen in a rainbow, produced by separation of the components of light by their different degrees of contraction according to lights wavelength.

• a band of colors, as seen in a rainbow, produced by separation of the components of light by their different degrees of reflection according to lights wavelength.

• a band of colors, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to lights wavelength.

• a band of colors, as seen in a rainbow, produced by collision of the components of light by their different degrees of refraction according to lights wavelength.

What is a rainbow

• A continuous spectrum

• A single spectrum

• A continuous light

• A duo spectrum

What is the doppler effect? (pick the best answer)

• defined as a noticeable change in the frequency of sound or light as the moving source APPROACHES the still observer.

• defined as a noticeable change in the frequency of sound or light as the moving source PASSES the still observer.

• defined as an unnoticeable change in the frequency of sound or light as the moving source passes the still observer.

What is Parallax Technique

• a method of measuring DISTANCE indirectly by creating an imaginary TRIANGLE  between an observer and an object whose distance is to be estimated.

• a method of measuring DISTANCE  indirectly by creating an imaginary RECTANGLE  between an observer and an object whose distance is to be estimated.

• a method of measuring VOLUME  indirectly by creating an imaginary TRIANGLE  between an observer and an object whose distance is to be estimated.

What is the baseline of Triangulation?

• the orbit of the sun

• The Diameter of the moon's orbit

• Diameter of Earth's Orbit

• Diameter of the sun's orbit

The color of emitted light with the LONGEST wavelength is

• violet

• green

• red

• indigo

The color of emitted light with the SHORTEST wavelength is

• violet

• green

• red

• indigo
