Scientist use a light meter to show how light in shining on a surface !
you stick itin the air and wave it about
A lux or lumens meter or in terms of mesurements lux or lumens
Scientist use physics for all sorts of things. Scientist can use Newtons and other gravity-related laws to work out the trajectory of a crashing satellite. If scientist wanted to, he could look use molecular physics to predict how chemicals will react. Scientist is a pretty cool guy.

The product of wavelength and frequency is equal to the propagation speed of the wave. For light waves, this is the speed of light. cw: Wavelength = W meters, Frequency = F per meter W meter X F per meter = dimensionless quantity. The speed of light, c, is typically measured in units of m/s or 3(10^8) m/s. OK, some use a dimensionless speed of light, where c=1. But I don't see how that follows from the general question.
no they don't

The scientist should use a light microscope.
Scientist can use light to move matter. For example, with directed beams of light, scientist can levitate, trap and grip small materials. The matter has to be surround by light entirely for this to work.

A scientist might use a model as a research method for a few reasons. This model could tell the scientist how something moves for example.
When the scientist is trying to represent an object or a system.

Being a scientist I like to use light as light. But light is mainly photons.
Typically, a light meter. However, some may require the use of a color temperature meter as well.
