Ray Diagramming

When do we use "REAL" during ray diagramming

• When the image is inverted

• When the image is upright

• When the image is behind the mirror

• When the image is infront of the mirror

When an object is placed at the center of curvature concave mirror, the image is...

• real, upright, bigger than the object

• real, inverted, and bigger than the object

• virtual, upright, and bigger than the object

• real, inverted, and the same size as the object

It is the horizontal axis points in ray diagramming

• Principal axis

• focal point

• focal length

• center of curvature

We can locate the image in a ray diagram if the three lines

• is parallel

• is diverging

• is converging

• is intersecting

Reorder the following steps in ray diagraming in concave mirror.

• From the side of the mirror, the parallel line would reflect passing through the focal point.

• Draw the image, the tip must be on the point of intersection and the bottom, touching the principal axis.

• Locate the top of the object, then draw a line parallel to the principal axis going to the side of the mirror.

• The point where Ray 1 and Ray 2 meets is the location of the image.

• From the top of the object, draw a line that would pass the center of curvature (C), and the ray would reflect in the same direction after touching the side of the mirror.

Based on the diagram the image location is between ​ (a)   , orientation is ​ (b)   , size is ​ (c)   , and the type is ​ (d)  

• F and 2F

• inverted

• reduced

• real

• V and F

• virtual

• upright

• magnified

What is the purpose of a ray diagram in optics?

• To locate the image formed by lenses or mirrors

• To measure the speed of light

• To calculate the wavelength of light

• To determine the color of light

In a ray diagram, what does the point where the rays converge represent?

• The focal point

• The center of curvature

• The principal axis

• The vertex

Which of the following is true about the image formed by a concave mirror when the object is placed between the focal point and the mirror?

• The image is virtual and upright

• The image is real and inverted

• The image is real and upright

• The image is virtual and inverted

What happens to the rays of light when they pass through a convex lens?

• They converge

• They diverge

• They remain parallel

• They reflect back
