Slide 2

Sources of Light Anything that produces light is known as a light source. Light sources can be normal, eg. the sun, or simulated, for example, lights or TV screens. Snap to proceed onward Mike Turner, May 2004

Slide 3

Traveling Light goes from a light source in straight lines. We call these light beams. When we draw light beams, we should utilize a ruler, and we should dependably draw a bolt on hold to demonstrate the bearing the light is going in, far from the source. Snap to proceed onward Mike Turner, May 2004

Slide 4

Traveling Light goes effectively through air. We say it is straightforward . In the event that light hits a misty item, it can\'t go through. This causes a shadow, as the light beams can\'t twist around the article. A few materials, eg. following paper, will let some light through, however we can\'t see through them plainly as though we were looking through a straightforward material, for example, glass. We say these materials are translucent . Snap to proceed onward Mike Turner, May 2004

Slide 5

Why We See Things We see things when beams of light from them enter our eyes. The beams of light can travel specifically at us on the off chance that they are from a light source, for example, from a light hulb. Be that as it may, we see most things since they mirror some light at us. Snap to proceed onward Mike Turner, May 2004

Slide 6

The Eye and the Camera The eye and the camera both work in a fundamentally the same as way. They each have a gap which permits light beams in, and produce a reversed (topsy turvy) picture. Beams of light go every which way from the head, however the greater part of them can\'t get into the container. Be that as it may, envision a beam of light from the highest point of the head that is heading towards the pinhole. (Click). Envision another beam of light going from the base of the head. This winds up at the highest point of the picture. We wind up with a picture that is upset. The Eye Click to proceed onward Mike Turner, May 2004

Slide 7

Reflection and Scattering When light hits an item, some of it is reflected. What amount is considered depends the shading (see later), and how harsh or smooth the surface is. A mirror has an exceptionally smooth surface and is an amazingly decent reflector. Most surfaces have an unpleasant surface, and they disseminate the light every which way. Street surafces are harsh, however when the surface is wet water fills in the gaps and the smooth surface turns out to be exceptionally glossy as it mirrors significantly all the more light.

The Law of Reflection If we sparkle a beam of light at a mirror we can foresee how the beam will ricochet off. Snap to proceed onward Mike Turner, May 2004

glass Bending Light - Refraction Air A beam of light alters course when it goes into an alternate substance. This is called refraction . Mike Turner, May 2004

Refraction At Work A fish swimming submerged looks to an onlooker over the water to be in an alternate position to where it really is. Keep in mind the coin in the container trap! Investigating water Click to proceed onward Mike Turner, May 2004

Slide 17

White Light? What we consider as white light is really a blend of all shades of light. Sir Isaac Newton chose that white light is comprised of seven hues : Red Orange Yellow Green Blue Indigo Violet We now realize that the human eye can recognize a huge number of various hues and shades. We can utilize a platitude, for example, : Richard of York gave fight futile ✩ Try to think about your own idiom to help you recollect the shades of a range. Newton\'s crystals Click to proceed onward Mike Turner, May 2004

Slide 18

Prisms Red Orange Yellow Green Blue Indigo Violet White light Dispersion of white light to create a range happens on the grounds that a few hues refract more than others. Mike Turner, May 2004

Slide 19

Red Filter Blue Filter Color Filters When white light is shone towards a shading channel, not every last bit of it is transmitted through the channel. The red light goes through the channel. The various hues are assimilated. This time blue light goes through the channel. The various hues are ingested. Snap to proceed onward Mike Turner, May 2004

Slide 20

Mixing Colors We can blend hued light to shape different hues. Blending light is altogether different to blending paints. The three essential hues are red, green and blue. These are the main hues that a TV screen produces. The entire picture is comprised of red, green and blue dabs! At the point when blended in sets these produce the three auxiliary hues, cyan, red and yellow (these are the three shaded inks you find in a shading printer).

Colored Objects A green item looks green since it reflects green light and ingests alternate hues. Could you clarify these cases? Snap to proceed onward Mike Turner, May 2004

Slide 27

Why do diverse items look changed hues? We see non-brilliant articles since they reflect light at us. ✩ RED items look red since they reflect just RED light ✩ BLUE articles look BLUE because they reflect just BLUE light Click to proceed onward Mike Turner, May 2004

Slide 28

Remember! Just RED light can traverse a RED channel Only BLUE light can get past a BLUE channel Click to proceed onward Mike Turner, May 2004

RED question and BLUE channel BLUE channels just let through BLUE light. The RED light gets retained RED articles reflect just RED light No light arrives so the item looks BLACK Click to proceed onward Mike Turner, May 2004

Slide 32

1. Attract an outline to show how we see a non-brilliant red article in white light, your graph ought to show why the item seems red. The knob produces white light. The RED article reflects RED light into our eye, every single other shade of light are consumed by the item . Snap to proceed onward Mike Turner, May 2004

Slide 33

2. What shading would a red item show up in red light? RED 3. What shading would a blue article show up through a blue channel? BLUE 4. Why do dark articles seem dark in white light? Since they ingest all shades of light. 5. What shading would a blue article show up through a red channel? Dark Click to proceed onward Mike Turner, May 2004
