spectrum of light
Understand the Problem
The question is asking about the spectrum of light, which refers to the range of different wavelengths of light emitted by sources like the sun or artificial lights. This typically includes visible light but may also encompass ultraviolet and infrared waves.
Answer
Electromagnetic spectrum ranges from radio waves to gamma rays; visible light spans 380 nm to 750 nm.
The electromagnetic spectrum includes ranges from radio waves to gamma rays. Visible light, which the human eye can see, is part of this spectrum and comprises wavelengths from approximately 380 nm to 750 nm.
Answer for screen readers
The electromagnetic spectrum includes ranges from radio waves to gamma rays. Visible light, which the human eye can see, is part of this spectrum and comprises wavelengths from approximately 380 nm to 750 nm.
More Information
The electromagnetic spectrum is organized by frequency or wavelength, with visible light being only a small part, perceivable by the human eye. This spectrum also includes radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays.
Tips
Confusing the order of electromagnetic waves and their corresponding wavelengths or frequencies is common. Understanding their correct sequence helps avoid mistakes.
