presume that you are asked to find the image position in a problem involving a lens you are specified the object position and you are told that the
presume you are asked to find the characteristics of the image of an actual physical object formed by a single lens and you obtain a negative value
q what do the negative sign tell you about the imagea single lens is utilized to form an image of an actual physical object you compute the image
q movement of principal rayin every case a principal ray moves from the head of the object to the plane of the lens it passes through the plane of
principle ray iii preliminary from the head of the arrow that the object is ray iii travels directly toward the focal point on the other side of the
principle ray ii preliminary on the object side of the lens ray ii heads toward the plane of the lens along a line that is parallel to the principle
q situation of the converging lens - principle ray 1principle ray i the easy one just as in the case of the converging lens this ray goes straight
q describe diffrent principle of raysprinciple ray i the easy one it hits the lens smack dab in the middle as well as passes straight on
which of the subsequent is a principal ray for the case of an actual physical object and a convex converging lens indicate all that applyansin the
the index of refraction of a particular medium is nearly the same for all wavelengths hence we often associate a single value the average value of
on transitory from a medium with one index of refraction to a medium with a different index of refraction light is typically both reflected and
a ray of light itinerant in air passes through a flat plate of glass refraction takes place where the refraction does occursansrefraction takes
a ray of light in air is occurrence upon a flat piece of glass how acts the path that the light travels along when it is in the glass compare with
in structuring the image does light from the object necessarily pass through the location of the imageansno in reality in the case of a plane mirror
presumptuous that it is understood that the object is in front of the mirror and anything on the other side of the mirror is behind the mirror is the
question as-per to the law of reflection the angle of reflection is equal to the angle of incidence an angle is at all times an angular separation
questiona person is doing effort to locate the image of an object of a plane mirror by means of a ray-tracing diagram the person draws a ray by the
questionfor a plane mirror that is true of the normalfeedback the usual is an imaginary line that passes through the point of incidence and is
question why are polarized sunglasses are effectiveanswerif it werent for the fact that surfaces that produce glare have a tendency to absorb
quewhen light is vertically polarized what is it regarding the light that is verticalansit is the electric field somewhat than the magnetic field
quecompletely un-polarized light of intensity io is occurrence on a polarizer whose polarization direction makes an angle of 150 degrees amid respect
a polarizer polarization consists of long-chain polymers aligned in a preferred orientation how does that orientation evaluate with the direction of
it is desired to lessen the reflection of light by the outer surfaces of the objective lenses of a pair of binoculars these surfaces are the foremost
in terms of the wavelength of the pertinent light how thick must the layer of transparent optical coating on a transparent medium be in order to
diffraction is the spreading of light that takes place when it pass through a thin slit or small hole or passes by an obstacleanswerdiffraction is
