Why scientists keep revising the definition of the meter?
Revisions in the definition of the meter are intended to achieve greater precision.
Its orange red spectral line is how the modern day meter is defined?
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).
Meter is a derived unit or not?
In the SI measurement system, a meter is a "base unit". However, the definition relies on the prior definition of the second.
What is th definition of meter?
A 100 centimeters.
What elements orange red spectral line is how the modern day meter is defined?
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.
What is the definition for decimeter?
A decimeter is one tenth of a meter.
Definition of square meter?
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.

What is the definition of meter wave?
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.
What is the modern definition of photography?
The modern definition of photography is the process of producing images. This also includes, the process of taking or producing a photo.
