Sound Visualization Quiz

What setup is used to visualize sound vibrations in the video?

• A square plate with sand on top

• A camera capturing sound waves

• A laser beam reflected off a mirror

• A Bluetooth speaker inside a bowl with a stretched balloon and a mirror

What does the mirror represent in the setup?

• The movement of the rubber membrane

• The volume of air inside the bowl

• The frequency of the music

• The laser beam

What happens to the reflected beam when pure notes are played?

• It remains stationary

• It creates a figure of eight pattern

• It forms a messy, chaotic pattern

• It moves up and down on the wall

What causes spikes in amplitude when the frequency is decreased?

• Playing pure notes

• Using a laser to interrogate the movement

• Hitting the resonating frequencies of the volume of air inside the bowl

• Combining multiple frequencies

What patterns are observed as the pitch is decreased?

• Oval shape and circular pattern

• Messy and chaotic pattern

• Spikes in amplitude and straight lines

• Figure of eight and funny pattern

What happens when different frequencies are layered on top of each other?

• They cancel each other out

• They produce a chaotic pattern

• They form a straight line

• They create mad shapes and patterns

What did the speaker use to sweep through the frequencies with precision?

• A camera

• A laser beam

• A mirror

• JavaScript code

What did the speaker notice about the camera's representation of the laser's path?

• Blurry and indistinct path

• Straight line with no breaks

• Multiple starting and finishing points

• No difference from the live experience

What is Skillshare?

• A video editing software

• A camera brand

• An online community for creative people
