We call the ray of light that strikes a reflective surface an incident ray, and the ray that bounces back a reflected ray the angle of incidence , , is the angle between the normal —the line perpendicular to the reflective surface—and the incident ray. Chapter 5 light b) incident rays parallel to each other but not parallel to the principal axis : study the diagrams above and fill in the blanks in the following sentences. Notes for neet physics ray optics photometry ray optics resolving limit and resolving power ray optics binocular ray optics reflecting telescope ray optics scattering of light ray optics dispersion through a prism ray optics prism ray optics defects in lens ray optics silvering of lens ray optics combination of lens. L1 what is light objectives aims this chapter is essentially an introduction to the wave theory of light correct, is the basis of the very useful ray model of light, which explains a great deal about how we see things the elements of the ray theory, called geometrical optics, will be explored in chapters l2 and l3.

Reflection of light laws of reflection 1st law: incident ray, reflected ray & normal all lie in the same plane 2nd law: angle of incident ray (i) = angle of reflection (r) regular vs diffused reflection regular reflection: occurs when light is reflected on a smooth surface light is reflected in the same direction and. Igcse physics 0625 notes topic 3: waves light and sound 1 topic 3 properties of waves including light and sound what is wave motion the wave motion is a means of transferring energy from one point to another a ray of light traveling along the normal is not refracted. Light refraction is the bending of light as it goes from one medium to another laws of refraction: (1) incident ray, refracted ray & normal are on the same plane (2) sine i/sine r is constant.

Physics light – reflection and refraction 1) principal focus : the principle focus of a convex mirror is the point on its principal axis to which a beam of light rays, initially parallel and close to the axis, appears to diverge after. A ray of light is the direction along which the light energy travels in practice a ray has a finite width and is represented in diagrams as straight lines a beam of light is a collection of rays. Light (reflection and refraction) notes for class 10 formulas download pdf 1 ray of light : a line drawn in the direction of propagation of light is called a ray of light.

Light rays from sun while coming towards earth suffers successive refractions from a rarer to a denser medium and so it bends towards the normal at each refraction these rays on earth appear to be coming from an apparent position of sun which is higher than its actual position. Class 12 physics chapter 9 ray optics and optical instruments notes – pdf download light waves can be bent and reflected to form new and sometimes altered images understanding how light rays can be manipulated allows us to create better contact lenses, fiber optic cables, and high powered telescopes. Page 1 of 8 physics i notes chapter 14: light, reflection, and color characteristics of light • light is an electromagnetic waveas shown below, an electromagnetic wave is a transverse wave consisting of mutually perpendicular oscillating electric and magnetic fields. Physics of light and optics justin peatross michael ware brigham young university august 14, 2008 preface this book provides an introduction to the eld of optics from a physics perspective it focuses primarily on the wave and ray descriptions of light, but also includes a brief intro. Using a ray/light box, shine a ray of light from the air into the glass mark the incident ray with crosses and where it enters the block, and do the same for the refracted ray draw your lines and you would note that the ray of light didn't travel straight through the glass.

Learn about and revise lenses, images, ray diagrams, refraction and transmission of light with gcse bitesize physics. Revision notes for o level physics coursework the notes available here are great for revision and studying on the go the o level physics content here is equivalent to the physics required to obtain american high school diploma. When a ray (broken line) of light travels from n2 into n1 it splits into a refracted ray and a reflected ray at the interface as the angle of incidence increases the refracted ray becomes. Light rays are not a physical thing, but we can make a beam of light that looks a lot like a light wave for physics experiments and to illustrate how light works.

The light reflected is partially polarized, meaning that it is a mixture of polarized light and unpolarized light the extent to which the reflected light is polarized depends on the angle of incidence and the refractive index of the two mediums. Hsc physics notes – from ideas to implementation 93 - 1 increased understanding of cathode rays led to the development of the television 1 explain why the apparent inconsistent behaviour of cathode rays caused debate as to whether they. Chapter notes: ray optics physics class 12 refraction of light at plane surfaces the phenomenon of bending of light rays at the boundary between two media is called refraction.

  • A ray of light is the straight line along which the light travelled and a bundle of light rays is called a beam of light laws of reflection of light the angle of incidence is equal to the angle of reflection, and.

Cbse notes for class 12 physics – ray optics and optical instruments cbse notes cbse notes physics ncert solutions physics 1 ray optics or geometrical optics in this optics, the light is considered as a ray which travels in a straight line it states that for each and every object, there is an image. The important properties of x – rays are: (i) the x – rays are the electromagnetic wave of wavelength 10a° to 05° (ii) the x – ray travels in vacuum with the speed of light ie 3 10 8 m/s (iii) they affect high penetrating power. Rays are perpendicular to the spherical wave fronts far from the source, the curvature of the wave front is small, so the wave front appears to be a plane then, the light rays will be nearly parallel rays from the sun are considered to be parallel when reaching the earth most visible objects are.
