Real image Definition and 19 Threads

I have a spherical concave mirror with focal length of 65cm, radius of curvature of 130cm. I hold the mirror close to the eye at approximate 45 degrees and I reflect an object below it as shown in the image. The distance between the object and the mirror is 90cm, that is more than the focal...

Hi there I am teaching resonance and standing waves in stringed instruments at the moment at high school. The theory states that a number of standing waves simultaneously (harmonics) exist in a naturally vibrating musical string, but with varying amplitudes, the 1 st harmonic being loudest...

Is it possible to get a real image of virtual objects, If so please explain with examples and some real life situations? Look at my assertion "rays will not pass through virtual objects so how it can form real image", is this possible, please help.

Suppose light rays from an object fall perpendicular to the surface of the plane mirror. Will the image be formed at +infinity(a virtual image) or -infinity(a real image)? I will be thankful for help!

Homework Statement My question is, are real images always inverted and virtual always erect? Homework Equations 1/v+1/u=1/f for mirrors and 1/v-1/u=1/f for lenses The Attempt at a Solution Consider a concave lens, with object at -x. the condition for a virtual image is v<0; i.e on the same...

Is there a simple way to determine or prove this? Real images are always inverted, and unlike virtual images can be projected onto a screen (I'm not even sure what this means to be honest). If I look at the back end of a spoon (convex mirror), the image is always upright and therefore virtual...

Hi there, i want to know as much as possible about this situation. I want to know the angles of vision for a real image, where can one see the image, the location of our eye to see it. Which factors determine this angle Thank you so much :D I hope this isn't a dumb question, thanks.

A plane mirror forms a virtual image of a real object placed in front of it and a real image of a virtual object placed in front of it. I can't picture the second case. Please show me a ray diagram showing real image formation by a plane mirror or just explain the case of real image formation by...

The question posed: "An object is located to the right of a mirror that in concave in its [the object's] direction. If the object sits on the focal point of the mirror, what answer best describes the image formed?" Our class is united in the notion that as the rays would be parallel...

That is, take the virtual image as the object for a second lens?

I do understand that we don't need a screen to view a real image, but why our eyes need to be far away from the lens than the image? Why can't we be exactly where the image would normally appear if we had a screen? Moreover, the image there is sharp because the rays converge exactly at that...

Hi all, This is probably a silly questions, but I want to be sure :). I'm wondering if a real image, created by a convex lens, can appear larger than the lens diameter itself. As an example, I'm thinking about the following: - I have a an object of height h_0=7.76" (display size of...

Homework Statement Doing some practice problems to prepare for upcoming exam and ran across this: A real image is a. One in which light does not pass through the image point but appears to diverge from that point b. One for which the magnification equal 1 c. An excellent image d. An...

I cannot seem to get the concept of real and virtual image. This is my understanding. If the light beams go to the reflecting surface(concave or convex mirror) then an image will be form assuming the reflecting beams meat at a point. If the image appears to be in front of the mirror(s' is...

So, the question I ask is simple : " Is a screen necessary to view a real image?" For example, when I view my image at the 'concave mirror' side of a spoon, a real image is visible. Now, according to my book the image location should be between Centre and Focus. So, is the image actually...

"real" image from concave mirror Ok so in we are currently doing mirrors and reflections in physics and from what I learned there are 2 types of images: real and virtual. I know that a virtual image is what you see INSIDE the mirror; but what does a real image looks like? I can't find anything...

how can we say that the image formed by a concave mirror is always real if object is virtual? please help

Normally we see a virtue image after light from the object reflects off a mirror. We then trace back to behind the mirror to a point where the virtue image came from. A real image is seen when light from the object projecting the image reflects off a screen or mirror and we see it with our...

Maybe it's just late, but I'm having an extremely difficult time proving that the minimum distance between an object and it's real image (geometric optics, thin lense equation) is 4f. I can see that it is true, however I'm unsure how to go about proving it mathematically.
