Presentation transcript:

Laterally Inverted An image that is laterally inverted means is inverted from left to right. The right side of the object appears as its left side, and vice versa.

Which is the object? Which is the image?

Ray model of Light Light moves in a straight line Luminous objects such as candles radiate light in all directions We depict this using a light ray Light ray: a line on a diagram representing the direction and path that light is travelling

Images and Reflections Light ray: a line on a diagram representing the direction and path that light is travelling\ Image: reproduction of an object through the use of light Reflection: the bouncing back of light from a surface

Reflection in a Plane Mirror incident ray reflected ray normal angle of incidence angle of reflection mirror

The Laws of Reflection The angle of incidence equals the angle of reflection The incident ray, reflected ray, and normal all lie in the same plane

How we see light Light reflects off of objects and enters our eye Because light moves in a straight line, our brains “assume” all light that enters our eyes travelled in a straight line

Properties of an Image: Plane Mirror An object in a mirror is laterally inverted Lateral inversion: The orientation of an image in a plane mirror that is backwards and in reverse order. The distance between the object and the mirror is the same as the distance between the image and the mirror

Characteristics of an Image (LOST) Location: what side of the mirror is the object on and how far away from the mirror is it? Orientation: how the image is orientated compared to the object. Upright or inverted. Size: the size of the image relative to the object. Larger, smaller, or the same size. Type: real or virtual.

Characteristics of an Image (LOST) for a Plane Mirror Location: Orientation: Upright or inverted. Size: Larger, smaller, or the same size. Type: real or virtual. Same distance from the mirror as the object
