To determine which electromagnetic wave corresponds to the provided wavelength of 0.000000000001 meters (or 1 picometer), we need to understand where this wavelength falls in the electromagnetic spectrum.
The electromagnetic spectrum is generally organized from the longest wavelengths (radio waves) to the shortest wavelengths (gamma rays):
- Radio waves: over 1 mm (10^−3 m)
- Microwaves: 1 mm to 1 m (10^−3 m to 1 m)
- Infrared: 700 nm to 1 mm (7 x 10^−7 m to 10^−3 m)
- Visible light: ~400 nm to 700 nm (4 x 10^−7 m to 7 x 10^−7 m)
- Ultraviolet: 10 nm to 400 nm (1 x 10^−8 m to 4 x 10^−7 m)
- X-rays: 0.01 nm to 10 nm (1 x 10^−11 m to 1 x 10^−8 m)
- Gamma rays: less than 0.01 nm (1 x 10^−11 m)
A wavelength of 0.000000000001 m (1 picometer) is much smaller than X-rays and falls within the range of gamma rays, which typically have wavelengths less than 0.01 nm (10 picometers).
Therefore, the correct answer for the electromagnetic wave represented by the question mark is:
Gamma Ray
