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.

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

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

• 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.

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

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

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
