Mount saint helen is an active stratovolcano and it was formed due to the subduction of the Juan de fuca plate.
Perhaps the most successful way we've been able to use light to transfer information is fiber optics. ... Through rapid changes in the light, you can send highly complex signals down the cable. These are most often used either for high speed internet connections, or for sending sound signals to home theater systems.
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
The answer is a meteor.
Meteors make flashing light when they enter the Earth's atmosphere. This is actually meteors on fire, because our atmosphere makes them burn when they come in contact, and crashes them under the pressure. This makes up for a beautiful sight on the night sky, and people often refer to the burning meteors as ''falling stars'', and make wishes as well.
