2 - 400 What is the speed of Wave B if the graph covers 1 second and 10 meters? F=1 Hz λ= 10 meters V= 10 m/s

2 - 500 Which wave has the fastest speed? If they are covering 10 meters in 1 second. They are all going 10 m/s

3 - 100 Echoes are an example of what wave behavior? Reflection

3 - 200 A straw seeming to bend in water is an example of what wave behavior? Refraction

3 - 300 Sound going around a corner is an example of what wave behavior? Diffraction

3 - 400 As you move away from a siren to the frequency of the siren does what? Decreases

3 - 500 What is the difference between Constructive Interference, Destructive Interference and Superposition Constructive – 2 waves add together Destructive – 2 waves cancel each other out Superposition – 2 waves pass each other without affecting each other

4 - 100 What is the main difference between Mechanical Waves and Electromagnetic Waves? EM waves can travel through a vacuum and mechanical waves need matter

4 - 200 Electromagnetic waves are what type of waves? Transverse (specifically 2 transverse waves – double transverse wave)

4 - 300 All objects made of matter emit EM waves, why? They all have charged particles

4 - 400 How can we tell how much energy an electromagnetic wave has? What about mechanical waves? EM = frequency Mechanical = amplitude

4 - 500 How do we create a magnetic field? How about an electrical field? Magnetic field – by changing electric currents Electrical field – by changing magnetic fields

5 - 100 What do we use infrared EM waves for? Thermo-imaging Tv remotes Cd drives

5 - 200 If an EM wave has a shorter wave length, what does that mean for it’s frequency? Energy? Higher frequency Higher Energy

5 - 300 Which has a longer wavelength Red light or Blue light?

5 - 400 What is one positive aspect of UV light and one negative for humans? Positive – vitamin D Negative – Sunburn/Skin Cancer
