Question

Which type of Remote sensing represents the single band of visible spectrum to produce black and white images?

• A. Hyper-spectral
• B. Multi-spectral
• C. Thermal spectral
• D. Panchromatic

Answer 1

Answer:

D. Panchromatic

• Panchromatic -Captures the entire visible spectrum in a single band, resulting in high-resolution grayscale (black and white) imagery.

• Multi-spectral: Uses several broad bands (e.g., Red, Green, Blue, Near-Infrared).

• Hyper-spectral: Uses hundreds of very narrow, contiguous bands.

• Thermal spectral: Detects heat (long-wave infrared radiation) rather than visible light.
