Answer: Curved mirrors often reflect a distorted image that looks different from how you look in real life. Low-quality mirrors are also likely to produce image distortions and give your face an asymmetrical appearance, which is perceived as ugly.
Explanation:
<span>The answer is heterogeneous mixture. A heterogeneous mixture is a combination of substances that are combined physically but not chemically. This is a mixture that is not uniform in composition. Its components can easily be separated from one another. For example, pile of soil is a heterogeneous mixture because it consists of different components.</span>
Answer: The variable that you manipulate is called the independent variable. The variable that you measure is called the dependent variable.
Answer: The light is slowed down by the prism, but the different wavelengths of light are all slowed down a different amount by the prism.
Explanation:
What happens here is that white light passes from a medium with an specific index of refraction (air) to another medium with a different index of refraction (the material of which the prism is composed).
Then, when light passes from a medium to another, its speed changes causing the deviation of the beam of light. However, we are talking about white light that is composed of different wavelenghts. So, since the frequency of light remains costant when passing from one medium to another, the different wavelengths change as a result of the change in speed.
This was first observed by Isaac Newton in the eighteenth century, when he found out that when a beam of light from the Sun, passes trhough a prism is decomposed in many different colors.
What is a hypothesis?
a tentative explanation for an observation
Definition of hypothesis in US English:
A supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
