Image formed by concave mirror; completed need someone to check

Click For Summary
SUMMARY

The discussion centers on calculating parameters related to a concave mirror used to examine a tongue bite. The object distance (s) is established as 10 cm, resulting in a virtual image distance (s') of -40 cm, indicating a virtual image. The focal length (f) is calculated to be 13.3333 cm, leading to a radius of curvature (R) of 26.6667 cm. The calculations confirm the accuracy of the solution provided by the user.

PREREQUISITES
  • Understanding of concave mirror properties
  • Familiarity with mirror equations: 1/s + 1/s' = 1/f
  • Knowledge of magnification concepts: Magnification = -s'/s
  • Basic grasp of focal length and radius of curvature relationship: f = R/2
NEXT STEPS
  • Review the derivation of mirror equations for concave mirrors
  • Explore the concept of virtual images in optics
  • Study the implications of magnification in real-world applications
  • Investigate the differences between concave and convex mirrors
USEFUL FOR

Students studying optics, physics educators, and anyone interested in the practical applications of concave mirrors in real-life scenarios.

Homework Statement



A person accidentally bit his tongue and wants to examine the bite by using a concave mirror. The mirror is placed 10 cm from the bite with the result that a virtual image of the bite appears 4 times actual size. Find the parameters s (distance from object to mirror), s' (distance from mirror to image), and R (radius of convex mirror).

Homework Equations


1/s + 1/s' = 1/f ; f=focal length
Magnification = -s'/s
f = R/2

The Attempt at a Solution



i got s = 10 cm
then using magnification formula (4 = -s'/s)
i got s' = -40 cm (negative b/c its a virtual image)
i then got focal length = 13.3333 using formula 1
so if f=R/2; R = 26.6667 cm

any input would be appreciated
