Details of the animation/ movie /software

When a beam of light strikes a rough surface it is reflected in different directions over a wide area. Such a reflection is called Diffused or Irregular reflection.

When a beam of light strikes a smooth surface it is reflected in a fixed direction. Such a reflection is called specular or regular reflection.

Light rays reflected from regular surface follow two laws of reflection:
1.) Angle of incidence = angle of reflection
2.) The incident ray, the reflected ray and the normal at the point of incidence lie in the same plane.

The image formed in a plane mirror is
· Virtual and upright
· Same size as the object
· Object distance = image distance

The image formed in a plane mirror is called virtual as it has no physical existence.

The image formed in the mirror is laterally inverted. Lateral inversion refers to the apparent left-right reversal of the image with respect to the object.

Keywords covered are : reflection, microscopic views, 3d planes, reflection from mirrors, regular and irregular reflection, lateral inversion, terminology, laws, reflection from point object & extended object, real & virtual images.......

If you are still unclear about the concepts, please refer the animation .

Q6: what is the diffrence between regular and diffused reflection? shraddha 14/4/2009 Ans: Q7: what is reflection pranay 6/2/2009 Ans: Q8: as bcoz light ray is a electro magnetic ray it should hav deflected in a great deal with the application of electric or magnatic field...but does it actually change???if not why??? shihab 19/12/2008 Ans: Q9: where is the best place to shine a light bulb and why? sareeta 7/5/2008 Ans: Q10: I was given a project to make a periscope, can you please help me to make a periscope sareeta 7/5/2008 Ans: Q11: how could a detective tell from a photograph,without seeing the sky,whether it is abright clear day or cloudly? sareeta 20/4/2008 Ans: Q12: how does the lightheat can be transfered using magnifying lense lopus 28/1/2008 Ans: Magnifying glass can only focus Heat light on to a spot, transfer as such does not take place Q13: can a convex mirror form a real image in any case? subhashini gopi 4/1/2008 Ans: No a convex mirror always forms a virtual image Q14: what is meant by a critical angle?/ Mai 20/9/2007 Ans: The critical angle is defined as the angle of incidence that produces an angle of refraction of 90-degrees. When a light ray approaches a less dense medium (air) from a denser medium (water) the bending is toward the surface. At a certain angle, the bending will be so high that the refracted beam will be directed right along the surface (angle of refraction is 90 degree to Normal) so none of it will get out into the air, the angle of incidence will then be the critical angle. Q15: what is meant by lateral inversion gracie 15/3/2007 Ans: When you look in the mirror the left side appears on the right and vice versa, for example of you are holding an apple in your right hand it appears in the left hand to you when you look in the mirror. This is called as lateral inversion, the mirror is thought to be inverting you, however this is an illusion, there is no left-right inversion, the mirror is simply reflecting back in a straight line every point on your body. Please refer our ambulance animation to understand this. Q16: a convwx lens is cut into two halves along a diameter, describe effect fahad 28/3/2006 Ans: 1) when you cut along a diameter, you get two plano convex lenses, now if they are kept jointed together they will keep on working like a convex lens, 2) if cut across the diameter the lens will divide into two parts but if again both parts are kept together will function as before as a lens is like prisms joined together
