Properties of light such as its brightness, color, and frequency can all be used to support which idea about light?
earnstyle [38]

Answer:

A) Light is made up of waves.

Explanation:

Light is a form of electromagnetic waves.

Electromagnetic waves consist of electric and magnetic fields that oscillate periodically in a plane perpendicular to the direction of motion of the wave, therefore they are transverse in nature.

All electromagnetic waves travel in a vacuum at the speed of light:

c=3.0\cdot 10^8 m/s

Moreover, electromagnetic waves are classified into 7 different types depending on their frequency and wavelength. From lowest to highest frequency (and so, from longest to shortest wavelength), we have:

Radio waves

Microwaves

Ultraviolet

Visible light

Infrared

X-rays

Gamma rays

Visible light is part of this electromagnetic spectrum, and corresponds to the part of the electromagnetic waves that our eye is able to see. In particular, we perceive waves of different wavelength and frequency as different colors: for instance, violet/blue light corresponds to the shortest wavelength that we can see, while red light corresponds to the longest wavelength that we are able to see.

Also, for visible light wave we can describe their brightness, which corresponds to the intensity of the wave, which is a property of all waves.

So the correct answer is

A) Light is made up of waves
