__________ mirrors are also known as diverging mirrors as the focus is found behind the mirror (virtual image) and is found by tracing back the reflected rays in a straight line.

Convex mirrors are known as diverging mirrors because the focus is found behind the mirror (virtual image) and is determined by tracing back the reflected rays in a straight line.

The middle of the "circle" created by a curved mirror is called its centre of ______________.

The middle of the "circle" created by a curved mirror is called its center of curvature. The center of curvature is the point located at the center of the imaginary circle that the mirror's curvature would create if extended.

Explanation

3. Where all reflected rays intersect after "bouncing off" a curved mirror is called the _________ (F).

The point where all reflected rays intersect after "bouncing off" a curved mirror is called the focus or focal point.

Explanation

The point where all reflected rays intersect after "bouncing off" a curved mirror is called the focus or focal point.

_______ mirrors are also known as converging mirrors as the light converges at the focus in front of the mirror and creates a real image.

Concave mirrors are also known as converging mirrors because they have a curved surface that causes light rays to converge at a focal point in front of the mirror. This convergence of light rays allows a real image to be formed.

Explanation

5. Ray diagrams are used to find the location of an image seen through a mirror.You need 2 rays to locate an image. The image is located where the rays _________.

Ray diagrams are used to locate the image seen through a mirror by tracing two rays. These rays are drawn from the object and follow the reflection laws at the mirror's surface. The point where these two rays intersect is the location of the image. Therefore, the correct answer is "intersect."

Explanation

6. The ________ is the exact point where the principal axis meets the mirror.

The vertex is the exact point where the principal axis meets the mirror. It is the point of intersection between the principal axis and the mirror surface.

Explanation

The vertex is the exact point where the principal axis meets the mirror. It is the point of intersection between the principal axis and the mirror surface.

Submit

7. The focal point for a concave mirror is to the _____.

The focal point for a concave mirror is always located to the left of the mirror. This is because a concave mirror is curved inward, causing light rays that are parallel to the mirror's axis to converge at a point in front of the mirror. Therefore, the correct answer is "left".

Explanation

Submit

This is the line drawn through the centre of the mirror( and meeting the mirror at 90 degrees perpendicular).

The correct answer for this question is "Principal Axis". The principal axis is the line drawn through the center of the mirror and meets the mirror at a 90-degree angle, perpendicular to the mirror's surface. The term "principal axis" is also commonly abbreviated as "PA" or "pa".

Explanation

Submit

9. Searchlights, car headlights and flashlights all use concave mirrors to create _________ beams of light.

Concave mirrors are used in searchlights, car headlights, and flashlights to create parallel beams of light. The reflective surface of a concave mirror curves inward, which causes the light rays to converge at a specific focal point. By placing the light source at the focal point, the reflected light rays will be parallel and create a concentrated and focused beam of light. This is why parallel is the correct answer.

Explanation

Submit

10. Telescopes and satellite dishes use concave mirrors to focus ________ __________ at the focal point. (We will discuss this more next Unit.)

Telescopes and satellite dishes use concave mirrors to focus electromagnetic waves at the focal point. The correct answer is "electromagnetic waves" because this is the type of energy that is focused by concave mirrors. It is important to note that the answer is not case-sensitive, as both "electromagnetic waves" and "Electromagnetic Waves" are considered correct.
