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: The Whiskey Rebellion was caused by a whiskey tax imposed by Congress in 1791. In 1788, the federal government and the state governments were still obligated to pay off debts resulting from the American Revolution (1775–83).
Answer:
1. Farmers markets ⇒ Local Food Movements
Local food movements aim to connect consumers and farmers of the same locality such that the local economy grows, consumers get fresh food and the farmers get to sell their produce. Farmers markets are a broad feature of these movements.
2. Free range chickens ⇒ Value-added speciality crops, organic farming.
Free range chickens are allowed to graze for themselves instead of being fed industrial food. This means that they were farmed organically.
3. Food subscription services ⇒ Community-supported Agriculture.
Community-supported agriculture works by connecting consumers and farmers such that the consumers can subscribe to the farmer's harvest.
4. People not having a grocery store near them to get fresh food ⇒ Food Desert.
As the term implies, a people in a food desert will be unable to get fresh food in their area because much like a desert which lacks certain resources, their area lacks food.
5. Growing plants on a rooftop in the city ⇒ Urban Farming.
Some people have taken to urban farming where they farm in the cities and towns. As these areas do not have enough areas to farm, people have had to improvise and rooftop farming is one of the ways they did.
6. When coffee plantation workers in LDCs get more money for their coffee products in better working hours/conditions ⇒ Fair Trade.
Farmers getting paid the right or close to the right wages for the work they put in especially from Less Developed Countries (LDC) means they are getting a fair trade because they are receiving enough or close to enough compensation for their work.
