Pinhole Cameras Converging & Diverging Lenses

Pinhole Cameras Converging & Diverging Lenses. Pinhole Image. Pinhole Camera. Image is upside down and left to right reversed Size of image is determined by distance from pinhole to screen/film The smaller the pinhole, the clearer the image & the dimmer the image. Pinhole Camera Picture.

Thin Lenses

Thin Lenses. Chapter 15. What is a lens?. A transparent object that refracts light rays, causing them to converge or diverge to create an image. Converging Lenses. A converging lens is thicker at the middle than it is at the rim

Chapter 25

Chapter 25. The Reflection of Light: Mirrors. LAW OF REFLECTION The incident ray, the reflected ray, and the normal to the surface all lie in the same plane, and the angle of incidence equals the angle of reflection. In specular reflection, the reflected rays are parallel to each other.

Physics

Physics. Review. Lenses. REMEMBER. Convex lenses are thicker in the middle and thus they converge light rays. Concave lenses are thinner in the middle and thus they diverge light rays. Click. Lenses. Just as with concave mirrors, the characteristics of the image

Thin Lens

Thin Lens. Chapter 15.2. Bending of Light. Any transparent object that is curved with affect the path of light rays. Ex: Glass bottle full of water will affect the image of an object.

Refraction: bending of light at the interface of 2 different materials

Refraction: bending of light at the interface of 2 different materials. Refraction. In the Refraction lab you saw the laser light change angles when it traveled from air into water or oil. Light changes directions because it changes speed: it actually travels slower in water, glass, oil, etc.

Chapter 36: Image Formation

Chapter 36: Image Formation. Suggested Problems: 3,7,9,23,28,33,45,73,77. Flat Mirrors. p is called the object distance q is called the image distance ? 1 =? 2. Virtual Image: formed when light rays do not pass through the image point but only appear to diverge from that point.

Telescopes and Microscopes

Telescopes and Microscopes. Question:. When you look through the converging eyepiece of a telescope, you see an enlarged image of a distant object. If you replace the eyepiece with one having more curvature and a shorter focal length, will the image you see appear larger or smaller?.

The Thin Lens Equation

The Thin Lens Equation. Examples using lenses. A Converging/Convex Lens. In convex lenses, f is positive d o is always positive d i can be positive or negative. A Diverging/Concave Lens. In concave lenses, f is negative d o is always positive d i is negative. The Equation.

Plane Mirrors

Plane Mirrors. Mirror Image. Viewing a mirror shows an image. Light rays from an object reflect from the mirror. The eye traces the rays back to an image. Plane Mirror. The law of reflection applies to each ray from the source at the mirror.
