Using Mirrors to form images Flashcards
What is a plane mirror?
A plane mirror is a smooth mirror, usually found in a home.
How do you know your reflection is in a plane mirror?
In a plane mirror, your reflection will be equal distance into the mirror as you are away from the mirror, the orientation will be the same, and your size will be the same
What is the only difference in the reflection in a plane mirror?
Your image is reversed.
What is a concave mirror?
A concave mirror curves inwards.
What is a focal point?
The focal point is the place where all the reflected rays meet.
What is converging?
When all the rays meet at one point they are said to be converging — joining
how does a concave mirror change the image?
From a distance the image is small and upside down, as the item gets closer it stays upside down but gets larger. As the item gets past the focal point, the image becomes larger than in real life and goes upright.
what are some uses for a concave mirror?
Concave mirrors are used in flashlight, car headlights and lighthouses because the focal point concentrates the light. Shaving and make up mirrors enlarge the image to give greater detail
What is a convex mirror?
A convex mirror curves outwards.
How are the light rays reflected in a convex mirror?
The light rays are reflected as if the focal point was behind the mirror.
How do object appear in a convex mirror?
Convex mirrors make the object appear smaller, and more objects can be seen in the mirror.
Where are convex mirrors used?
Convex mirrors are used in security mirrors in stores and libraries. They widen the view in vehicle side mirrors.d
