Propiedades de la imagen en el espejo cóncavo

What is the focal point of a concave mirror?

• The focal point of a concave mirror is the point where the reflected rays of light converge in a direction opposite to the principal axis of the mirror.

• The focal point of a concave mirror is the point where the reflected rays of light converge parallel to the principal axis of the mirror.

• The focal point of a concave mirror is the point where the reflected rays of light converge at right angles to the principal axis of the mirror.

• The focal point of a concave mirror is the point where the reflected rays of light converge in a dispersed manner to the principal axis of the mirror.

What is the difference between a real image and a virtual image in a concave mirror?

• The real image is formed when the light rays appear to come from a point behind the mirror, while the virtual image is formed when the light rays are reflected directly in the mirror.

• The real image is formed when the light rays are reflected directly in the mirror, while the virtual image is formed when the light rays cross after being reflected in the mirror.

• The real image is formed when the light rays cross after being reflected in the mirror, while the virtual image is formed when the light rays appear to come from a point behind the mirror.

• The real image is formed when the light rays appear to come from a point behind the mirror, while the virtual image is formed when the light rays cross after being reflected in the mirror.

How is the magnification of an image calculated in a concave mirror?

• m = i + o

• m = o/i

• m = i/o

• m = -i/o

What are the steps for the formation of an image in a concave mirror?

• The steps for the formation of an image in a concave mirror are: 1. Parallel rays of light converge towards the focal point. 2. The image is formed between the focal point and the surface of the mirror. 3. The image is virtual, upright, and magnified.

• 3. The image is real, inverted, and reduced.

• 2. The image is formed behind the mirror.

• 1. The rays of light diverge towards the focal point.

Draw a ray diagram to show the formation of an image in a concave mirror.

• Draw a principal axis passing through the center of curvature of the mirror and the vertex, then trace a ray parallel to the principal axis that reflects and passes through the focus, and finally draw a ray passing through the focus and reflecting parallel to the principal axis.

• Draw a ray passing through the focus and reflecting passing through the vertex.

• Draw a ray passing through the focus and reflecting parallel to the principal axis.

• Draw a ray passing through the center of curvature and reflecting parallel to the principal axis.

What is the equation of the mirror that relates the distance of the object, the distance of the image, and the focal length?

• o * i = f

• o + i = f

• 1/o + 1/i = 1/f

• o - i = f

What are the properties of the image formed by a concave mirror?

• Virtual, right and enlarged

• Real, left and reduced

• Real, right and reduced

• Virtual, left and reduced

What type of image is formed when an object is beyond the center of curvature of a concave mirror?

• Real, inverted and enlarged image

• Virtual, inverted and reduced image

• Real, upright and enlarged image

• Real, inverted and reduced image

How does the position and nature of the image change as the object approaches the concave mirror?

• The image becomes larger, virtual, and approaches the mirror.

• The image becomes larger, real, and moves away from the mirror.

• The image becomes smaller, virtual, and moves away from the mirror.

• The image becomes smaller, real, and moves away from the mirror.

What is the relationship between the object distance, image distance, and focal length in a concave mirror?

• f = do - di

• 1/f = 1/do + 1/di

• f = do + di

• f = do * di
