Sound Files, Part 1: Understanding Binary Code and Sound

What is the main topic of this lesson?

• History of computers

• Mathematics

• Binary code and sound

• Physics of light

What is sound primarily made of?

• Light waves

• Sound waves

• Magnetic waves

• Electric waves

What happens when sound waves hit a person's ear?

• The sound waves turn into light

• The brain interprets it as sound

• The sound waves disappear

• The sound waves stop vibrating

Why can't sound be heard in space?

• Sound waves travel too fast

• Space is too cold

• Sound waves are too weak

• There is no air to vibrate

Why do we need to convert analog sound to digital?

• To make it visible

• To change its color

• To store it on digital devices

• To make it louder

How many times per second does a computer measure sound?

• 10,000 times

• 20,000 times

• 44,100 times

• 100,000 times

How does a computer represent different tones in sound?

• Using shapes

• Using letters

• Using binary code

• Using colors

What is the significance of 44,100 measurements per second in digital sound?

• It reduces noise

• It makes the sound louder

• It changes the pitch

• It ensures high-quality sound

What does 16-bit sound mean?

• 16 possible tones

• 16 different sounds

• 16 sound waves

• 16 bits per sound sample

How many different combinations of tones are possible with 16-bit sound?

• 4 billion

• 65,536

• 256

• 1,000,000
