Just like other phenomena -- through experimentation and build theories to explain the results (light is probable one of these phenomena). Other times, we have a theory first and go on to do experiments to prove it (for example, theories of relativity).
Light is generally agreed to have two natures -- wave and particle. Scientists found light can result in an interference pattern with double slots, hence a wave. They also found that its energy is quantized (photon energies are in discrete values, not continuous, as you think in a wave) -- you can count number of photons! Another puzzle about light is that a photon has its associated energy but no mass (not that we can find).
What else can I help you with?
Why do scientists measure light intensity?
to know how is the light heavy
How do scientists know there's not another universe or more a few trillion light years away?
They don't.
How do you know blackholes exist?
It is a tricky question because black holes are invisible, but scientists know that they are exist because black holes distort light, so it kind of change the light and also it sucks everything into it, so when scientists see stars starting to disappear, thats mean there is a black hole.

How do scientists know so much about stars in distant galaxies?
Scientists use telescopes to observe and analyze light emitted by stars in distant galaxies. By studying the light's intensity, temperature, composition, and movement, scientists can gather information about the stars' age, size, distance, and other properties. This data helps scientists understand the behavior and characteristics of stars in those galaxies.
What do scientists call the bending of light?
Scientists call it refraction.
What are scientists that study light?
Physicists study light.
What can scientists learn from a stars light?
Scientists learn the temperature of the stars light for exampleif the star is red- it's cold but it's blue- it's hot and if it's WHITE- IT'S VERY HOT ! that's how you know the temperate of stars (Determining the color)
Why do scientists to investigation?
To know about scientists life
What do scientists know about the size of the universe?
We know that we have observed galaxies out to as much as 14 billion light years from us in every direction, and we have never seen an end to it yet.
How can scientists create a portal to a parallel universe?
Scientists do not know how to create a portal to a different universe. They don't even know if it is possible. Alternate universes are merely theories. In the television show The Flash, they are working on this and it may take Flash traveling the speed of light.
What do scientists have for snacks?
light snacks
