In digital media, sound and light are translated into

• A. Bitmaps
• B. Vectors
• C. Waveforms
• D. Fonts

Answer: (C)

In digital media, signals from both sound and light are represented as waveforms, which are time-based variations of a signal’s amplitude. Sound is literally a waveform: air pressure changes over time that, when recorded digitally, become a waveform of samples. Light, captured by sensors, is converted into electrical signals that vary as the light intensity or color changes, and those varying signals are described as waveforms too. Bitmaps describe static images as a grid of pixels, not time-based signals. Vectors define shapes mathematically, not time-varying signals. Fonts are designs for rendering characters, not how signals are represented.
