1. ECE Experiment 1 Purpose: The purpose of this experiment is to familiarize the student with essential equipment which will be used each week in this lab. Of particular importance are the circuit breadboard, oscilloscope, multimeter, function generator, and DC power supply. In addition, this experiment reviews concepts covered in ECE Breadboard: The breadboard is a platform.

2. Before the development of radio astronomy, scientists studied celestial objects only in visible light. However, visible light makes up only a small portion of the electromagnetic spectrum, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma zierisadpaubodishimeterlaikesand.xyzinfo was as though all this time astronomers had been looking at a painting while being able to see only a.

3. – (as opposed to being only held by their edges) • Large lens at bottom of telescope – (as opposed to to at the top of the telescope) • Possible to reduce chromatic aberration – (lenses bringing different colors of light into focus at slightly different places)

4. ••19 Figure shows two isotropic point sources of sound,S1 and S2. The sources emit waves in phase at wavelength m; they are separated by D zierisadpaubodishimeterlaikesand.xyzinfo we move a sound detector along a large circle centered at the midpoint between the sources,at how many points do waves arrive at the de- tector (a) exactly in phase and (b) exactly out of phase? .

5. For objects at room temperature this emission is in the infrared, so we cannot see it. But for a telescope measuring in the infrared this adds significant noise to the measurement (similar to optical telescopes being placed quite far from civilisation and its light pollution).

6. Dinosaur Scene - Observation and Inference Worksheet A time machine has been invented that travels into the past and takes pictures, sending them to the present. You are asked to look at one of the pictures and interpret what you see. __A__ 1. The volcano is erupting. __B__ 2. The camptosaurus is going to eat the stegosaurus.

7. The water wave in the figure also has a length associated with it, called its wavelength λ, the distance between adjacent identical parts of a wave.(λ is the distance parallel to the direction of propagation.)The speed of propagation v w is the distance the wave travels in a given time, which is one wavelength in the time of one period. In equation form, that is.

8. Sound - Lab 1. In the lab activity, you will examine sound waves as they are emitted from a moving source. Predict what will happen to the sound waves when the sound source is in motion. Record your prediction (hypothesis) as an “if then” statement. (For example: If you.
