One meter is the distance that light travels in a vacuum in 1⁄299,792,458 of a second.
Revisions in the definition of the meter are intended to achieve greater precision.
The modern definition of a meter is based on the speed of light in a vacuum, with the wavelength of the orange-red emission line of krypton-86 equaling 1,064,380.046 nm. This particular wavelength corresponds to a specific frequency that is used to define the meter in the International System of Units (SI).
In the SI measurement system, a meter is a "base unit". However, the definition relies on the prior definition of the second.

The orange-red spectral line used to define the modern meter is derived from the element krypton-86. Specifically, it corresponds to the transition between two energy levels in the krypton-86 atom, which emits light at a wavelength of 605.78 nanometers. This definition was established in 1983, where the meter is defined as the distance light travels in a vacuum in 1/299,792,458 seconds. This definition emphasizes the constant speed of light as a fundamental aspect of measurement.
1 Square Meter is the area enclosed by a length of 1 meter and a width of 1 meter. It is equal to 11.111... square feet.
A decimeter is one tenth of a meter.
"Modern theater" is often referred to as "modern drama." By definition, it is the development of drama from the beginning of the 20th century on.
This might be a "quick" definition of a taxi cab.
unit for measuring length
I don't think that there is a wave with that name; it might refer to a wave that has a wavelength of approximately a meter.
The modern definition of photography is the process of producing images. This also includes, the process of taking or producing a photo.
