Storing images and sound in binary Lesson Objective: Understand how a computer stores images and sound with binary numbers Learning Outcome: Complete the worksheet

Simple example: 2 bits per pixel Image is 8 bits by 11 bits The binary data is stored and the images can be reconstructed from this.

What does a sound ‘look’ like? http://www.physics-chemistry-interactive-flash-animation.com/electricity_electromagnetism_interactive/oscilloscope_description_tutorial_sounds_frequency.htm
