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:
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
Answer: Electron
Explanation:
Two type of microscopes that are used to view cells are optical and the electron microscopes.
The optical microscope, is also called the light microscope, and it uses visible light and lenses to magnify small objects and make them bigger. It is used in viewing cells as they appear big.
Electron microscope gives a high resolution images of specimens. The electron microscope is used in medicine to investigate tissues, cells, etc.
