What type of wave is a SOUND wave?


Longitudinal/Compressional/Pressure Waves


100

Which part of a wave is responsible for volume in a sound wave? (note: the image below is NOT a sound wave, since sound waves are longitudinal. However, we can draw sound waves as tranverse waves to show volume and pitch easier)

 

D - Amplitude

the larger the amplitude of a sound wave, the louder the sound is perceived

100

Which wave (1, 2, or 3) would be the LOUDEST VOLUME?


2 (highest amplitude)

100

Waves transfer ______, NOT _______, from one place to another.

energy, NOT matter

100

Why are reflected light rays important?

Because they allow us to see

200

What kind of wave is this? (in that the particles within the wave travel perpendicular to the energy in the wave, for example, particles go up and down, but energy goes left to right)


200

Which letter on the image is responsible for the pitch we hear? (note: the image below is NOT a sound wave, since sound waves are longitudinal. However, we can draw sound waves as transverse waves to show volume and pitch easier)

 

D - Wavelength

The shorter the wavelength, the higher the frequency, and the higher the pitch, of the sound.

200


Fastest - Steel (solid)

Medium Speed - Water (liquid)

Slowest - Air (gas)

200

AND WHY!? (what specific property gives it more energy?)

A, Shorter Wavelength = Higher Frequency = Higher Energy

200

The bending of waves is known as....

Refraction

300

This picture is considered a mechanical wave because it needs a medium to travel through.  But more specifically it could be called a ____________ wave because the energy and particles move together in the same direction (left to right). 


Longitudinal OR Compressional OR Pressure Wave.


300

What does the wavelength of a transverse or longitudinal wave measure the distance of?


Is measures the distance from crest-crest or trough-trough of consecutive waves

300

Which waves move fastest through particles that have free movement and are spread far apart?

What are light waves

300


AND WHY!? (what specific property gives it more energy?)

A- because higher amplitude = higher energy

300

If I'm wearing a blue and pink shirt, why can I see the colors blue and pink but not the other colors?

What is the colors blue and pink are being reflected while all other colors are being absorbed.

400

Waves can be broken into 2 main categories: Waves that HAVE TO travel through a medium, and waves that do NOT have to travel through a medium. 

What is the type of wave that includes transverse and longitudinal, and DOES have to travel through a medium??

Mechanical Waves

example: sound is a mechanical wave and needs a solid, liquid, or a gas to travel through.

400

1) Draw a Resting line across the middle of your whiteboard. This line represents 2 seconds of time.

2) Then, Draw exactly 6 transverse waves that all fit within your resting line.

3) Calculate the Frequency of this wave and write that on your whiteboard

6 waves / 2 seconds = 3 Hz

400

Based on the Electromagnetic Spectrum (EMS), which color of the visible light spectrum has the longest wavelength and why?

What it the color red because it has less energy, occurs less frequent, thus causing it to have the longest wavelengths.

400

Which wave has the highest total amount of energy? What 2 specific reasons make this true?

4 - Highest amplitude AND highest frequency


400

What is it called when sound is reflected?

What is known as an echo.

500

An example of a wave that DOE NOT require a medium are known as.....

What is Electromagnetic Waves

500

A ____________________ is a substance through which a wave can travel.

What is a Medium or Matter

500

What happens to the speed of a wave if the medium doesn't change?

What is the speed will remain constant.

500

A wave with a large amplitude carries more______________than a wave with a small amplitude

What is energy

500

What causes fish in an aquarium to appear where they are not?

What is refraction.
