400
What is the focal length?
Focal length = 90
500
A concave mirror forms an inverted, smaller image. Where must the object be placed?
Past 2 focal lengths from the mirror's surface.
500
A student looks through a lens and sees the object enlarged and upright. What must be true about the lens and object location?
It’s a convex lens with the object inside the focal length
500
A convex lens makes an inverted image that is magnified. Where is the object?
Between one and two focal lengths from the lens.
500
A convex lens forms a virtual image only when the object is where?
Inside the focal length
