Spectrum Lab 1.11.12
Stars and other objects in the Universe give off energy as electromagnetic radiation. The
electromagnetic radiation travels through space as energy waves of varying wavelengths. The
electromagnetic spectrum includes gamma rays, x-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves, Astronomers evaluate different types of electromagnetic radiation to gather information about objects in space.
Many telescopes have spectrographs which refract light from viewed objects in space. The spectrographs produce photographs of the electromagnetic spectrum of the objects, Additionally, light emitted by and object at certain colors of the spectrum provides information about the temperature of an object.

1. What is the average distance covered in 5 seconds?
7.4 meters.
2. Calculate the speed of your lab group's radio wave pulse by dividing the average distance by five seconds.
1.48 m/sec.
3. Pick an object or a wall that is less than two bus lengths away from your starting position. Measure time required for the radio wave pulse to walk from the starting position to the object or wall and back to starting position.
7.4 meters.

1. What is the average time required to walk to the object or wall and return to the starting position?
5.33 seconds
Calculate the distance to the object or wall by multiplying the average number of seconds times the calculated speed of the radio wave pulse and dividing the product by two.
2. What is the calculated distance to the object or wall?
3.9442 meters.
If your teacher instructs you to do so, use a measuring tape to measure the actual distance.
