A continuous spectrum is a spectrum that contains all wavelengths of light within a specific range, without any gaps or interruptions. This type of spectrum is produced by a hot, dense object such as a solid, liquid, or dense gas.
Examples of continuous spectra include:
1. The spectrum of an incandescent light bulb, which emits light across all wavelengths in the visible spectrum. 2. The spectrum of the sun, which emits light across all wavelengths from ultraviolet to infrared. 3. The spectrum of a heated metal, which emits light across all wavelengths due to the thermal motion of its atoms.

Continuous Spectra:
Continuous spectra are bands of light that contain a smooth, unbroken range of wavelengths. They do not exhibit distinct lines or gaps.
Examples of Continuous Spectra:
- Sun's spectrum: The Sun emits a continuous spectrum ranging from the visible light to ultraviolet and infrared wavelengths. - Incandescent light bulbs: Generate a continuous spectrum as the filament heats up and emits light of all visible wavelengths. - Stars: Most stars, including the Sun, produce continuous spectra due to the high temperatures and thermal radiation from their glowing surfaces. - Blackbody radiation: A perfect blackbody emits a continuous spectrum at any temperature above absolute zero (-273.15 °C). - Plasma: Gas that is heated to very high temperatures, such as in stars or lightning, emits a continuous spectrum. - Continuous lasers: Some lasers, such as argon lasers, produce continuous spectra that are monochromatic (single-wavelength) but spread over a range of frequencies. - Rainbow: A rainbow is formed when sunlight is refracted and reflected, and it contains a continuous spectrum of colors.
