Answer:
The law of reflection states that the angle of incidence = the angle of reflection.
Explanation:
Reflection is the phenomenon that occurs when a ray of light hits the boundary between two media and it is reflected back into the first medium.
In such a situation, we call:
- angle of incidence: it is the angle between the direction of the incident ray and the normal to the surface
- angle of reflection: it is the angle between the direction of the reflected ray and the normal to the surface
There is a precise relationship between the angle of incidence and the angle of reflection. In fact, the Law of Reflection states that:
- The incident ray, the reflected ray and the normal to the surface all lie within the same plane
- The angle of reflection is equal to the angle of incidence
The inner membrane has many overlapping folds called cristae. Inside the inner membrane there is the mitochondrial matrix, it contains enzymes that are used in creating ATP.

Answer:
<em>b. Observe the radio waves coming from all dark matter; from the strength of the radio waves from each cluster, estimate the amount of dark matter needed to produce them.</em>
<em></em>
Explanation:
The universe is thought to be made up of 85% dark matters. <em>Dark matter is called dark because it does not appear to interact with the electromagnetic field, which means it doesn't absorb, reflect or emit electromagnetic radiation, and is therefore difficult to detect. This means that option b is wrong since radio wave is an electromagnetic wave</em>. Dark matter is a form of matter that makes up about a quarter of the total mass–energy density of the universe. Dark matter was theorized due a variety of astrophysical observations and gravitational effects that cannot be explained by accepted theories of gravity unless there were more matter in the universe than can be seen.
