Please answer questions 1 -20 for each answer look at the picture that I have attached for each question before answering the questions. I have labeled them question 1…..

1. The lasers are made from stacking light waves that add together into a larger wave in a process known as _____.

• destructive interference.
• constructive interference
• radio interference
• gamma ray interference

2. The light waves have that particular interference from question #1 because they are emitted _____.

• in phase
• out of phase
• in perpendicular directions
• in thoughtless rage

3. The emission of the light waves in the lasers allows them to overlap properly to create larger waves, which means that _____ overlap.

• the waves do not
• the troughs of one wave and the crests of another
• identical parts of the two waves
• only fifty percent of one wave and another wave

4. The lasers are red, meaning that they are giving off light in the _____ region of the electromagnetic spectrum.

• radio
• microwave
• visible light

8. The magnitude of the electric current is inversely proportional to the _____ of the circuits in R2D2.

• voltage
• electric current
• resistance
• interference

9. The setting sun is actually visible after it has dropped below the horizon due to the bending of light waves entering the atmosphere at a non-perpendicular angle to the surface, a process known as _____.

• reflection
• refraction
• constructive interference
• destructive interference
