Object located in focus (d0= F'). The figure below shows an arrow-shaped object, placed in front of a convex lens at a distance d0 equal to a focal length (d0=F'). Draw the following rays in the figure: ray parallel to the optical axis, central ray. Don't forget to put the direction on each ray, both the incident rays and the transmitted rays. Label each ray with its name. Image characteristics for Case 5: Object located in focus (d0= F'). Cho
Applications Of Reflection Of Light
When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.
Sign Convention for Mirrors
A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
Case 5: Object located in focus (d0= F'). The figure below shows an arrow-shaped object, placed in front of a convex lens at a distance d0 equal to a focal length (d0=F'). Draw the following rays in the figure: ray parallel to the optical axis, central ray. Don't forget to put the direction on each ray, both the incident rays and the transmitted rays. Label each ray with its name. Image characteristics for Case 5: Object located in focus (d0= F'). Choose the ones that apply:
a) Virtual
b) Real
c) Inverted
d) Increased
e) No image is formed
f) Equal size
g) Reduced
h) Erect
Case 6: Object located between the focus and the vertex of a convex lens (d0< F'). The figure below shows an arrow-shaped object, placed in front of a convex lens at a distance d0 less than a focal length (d0<F'). Draw the following rays in the figure: ray parallel to the optical axis, focal ray, central ray. Draw the image of the arrow, indicate in the same figure from where to where di is (image-lens distance). Don't forget to put the direction on each ray, both the incident rays and the transmitted rays. Label each ray with its name. Image characteristics for Case 6: Object located between the focus and the vertex of a convex lens (d0 < F'). Choose the ones that apply:
a) Virtual
b) Real
