To draw an image formed by compound microscope first draw a straight horizontal line (principle axis) now make a lens, take its focal length about 1.5cm at both sides, now at one side draw an object (arrow facing up) but smaller than the lens. make two rays from the tip of the object (arrow head), make one ray strike the lens straight and refract it through that focal length of the lens which is opposite the object, make second ray passing straight through the optical center of the lens and extend both rays, the point at which both rays cut each other make an image arrow vertically straight but up side down from principle axis, an consider this image as an object an make another lens bigger and opposite side of the first lens, now from the arrow head of the image (considered as object) make two rays towards the second lens, first striking straight the lens and again refracting from focal length of other side, second rays passes straight through optical center of lens, extend these rays but from back side, the point at which they coincide make the final image pointing down from the principle axis.

Describe compound microscope with ray diagram?

A compound microscope consists of two lenses: an objective lens and an eyepiece. The objective lens forms a real and inverted image of the object being viewed, which is then magnified by the eyepiece. A ray diagram would show parallel rays of light from the object converging at the focal point of the objective lens, then producing a virtual image that is further magnified by the eyepiece.


How would you trace ray diagram that shows all the images?

Ray diagrams are drawings that use simple geometry to locate an image formed by a mirror. In order to draw a ray diagram, first sketch the situation; draw the location and arrangement of the mirror and the position of the object with respect to the mirror. Construct the drawing so that the object and the image distances are proportional to their actual size. Then, draw to rays on your diagram. Draw the first ray from the object perpendicular to the mirror's surface. Since it makes and angle of 0 degree with the normal to the mirror, the angle of reflection also equals 0 degree, causing the ray to reflect back on itself. Draw the second ray from the object to the mirror, but this time place the ray at an angle that is not perpendicular to the surface of the mirror.Then draw the reflected ray. Next, trace both reflected rays back to the point from which they appear to have originated, which is behind the mirror. Use dotted lines to draw the rays to distinguish them from the actual rays of light. By continuing this process for all other parts of the object, you will be able to locate the complete virtual images for the object.

How to draw a ray diagram for a concave mirror?

To draw a ray diagram for a concave mirror, follow these steps: Draw the concave mirror as a curved line with a focal point (F) in the middle. Draw the object (usually an arrow) outside the mirror, beyond the focal point. Draw three rays: one parallel to the principal axis that reflects through the focal point, one through the focal point that reflects parallel to the principal axis, and one that goes through the center of curvature and reflects back on itself. Where the reflected rays intersect is where the image will form.

How do you draw a diagram of how a shadow is made?

It seems that you are asking about a ray diagram, or ray trace. One of the links below is a picture of a basic ray diagram. It shows how to trace the extent of a shadow cast by an opaque object on a screen. Basically, draw a line from the light source to an edge of the object and continue to where it touches the screen (a point source is easiest, but extended source is more accurate in that it shows where shading is and why). If you draw lines from the light source to several parts of the object, it builds a more accurate picture. This illustrates the phenomenon that light can (hypothetically) project an infinite number of rays (another way to look at it, a wavefront) to cast the exact shape of the object on a background.


How do you draw a ray diagram for an object placed in front of a convex lens?

To draw a ray diagram for an object placed in front of a convex lens, first draw the principal axis and the lens. Then, draw three primary rays: one parallel to the principal axis that passes through the focal point on the other side of the lens, one passing through the center of the lens which continues straight, and one passing through the focal point on the same side of the lens which emerges parallel to the principal axis. The point where these three rays intersect will give the image location.
