QOTD:

1. What is a wave? (2/14)

2. Draw a wave with a high amplitude and a high frequency. Draw a wave with a low amplitude and a low frequency. (2/26)

3. What is the relationship between... (3/2)

a. energy and amplitude

b. energy and wavelength

c. frequency and wavelength

d. frequency and speed

4. What effect does changing the amplitude of light have? (3/6)

5. Which was a better way of sending signals in the telephone activity? Explain.

6. Why is parity check a better way to check a signal than sending the signal multiple times?

VOCAB:

1. Wave - a disturbance that transfers energy from place to place

2. Medium - the material a wave travels through

3. Mechanical wave- A type of wave produced when a source of energy causes a medium to vibrate.

4. Transverse wave- A type of wave that moves the medium at right angles to the direction in which the wave travels. (ex: the jumprope)

5. Longitudinal wave- A type of wave that moves the medium parallel to the direction in which the wave travels. (ex: the slinky)

6. Transmission - the movement of a wave through a medium

7. Reflection - the bouncing back of an object or a wave when it hits a surface it cannot pass

8. Absorption - wave energy gets absorbed by atoms and turned into heat

9. Electromagnetic Wave - transverse waves that transfer electrical and magnetic energy AND do not require a medium

10. Refraction - the bending of waves as they enter a new medium at an angle

11. Analog signal - a continuous wave that changes over time

12. Digital signal - a discrete wave that carries information as either 1 or 0

13. Continuous data - data that has infinite possibilities

14. Discrete data - data that has a limited number of possibilities

15. Parity- whether a # is even or odd. Can be used to check a signal
