What is the focal length of a concave mirror if it converges light to a point?
Think about the direction in which the light meets.
Define the term 'image distance'.
Consider if the image is real or virtual.
What does the Mirror Equation relate?
Think about the basic concepts of optics.
True or False: The focal length of a convex mirror is always positive.
Recall the sign conventions for mirrors.
An object is placed 50 cm from a concave mirror with a focal length of 15 cm. Calculate the image distance and describe the nature of the image.
Carefully solve the equation step by step.
A convex mirror has an object placed 30 cm in front and a focal length of -10 cm. Find the image distance and explain its properties.
Don’t forget to consider the sign conventions.
