A. towards the focal point of the mirror. Question 3 (1 point) A concave mirror has a focal length of 4 cm. A candle with a height of 9 cm is 13 cm away from the mirror. The image on a convex mirror is always virtual, diminished and upright. 4. B. as from the focal point of the mirror. Convex Mirrors We give the definition of convex mirrors in previous sections. Use this online convex mirror equation calculator to find the focal length, image and object distance. Let’s start with the reflection of light with special examples. The image created by a convex lens is erect and virtual since the focal point (F), and center of curvature (2F) are both imaginary points within the mirror that cannot be reached. 1. In convex mirrors, ray coming parallel to the principal axis goes after reflection as if it comes from the focal point of the mirror. Now we will examine the reflection of light from this type of mirrors and image formation in convex mirrors. Hence the focal length cannot be determined directly. C. through the center of the curvature of the mirror c) The properties of image : – Upright – Smaller – virtual. Light strikes a convex mirror parallel to the axis will be reflected …. Your Answer: Answer Question 2 (1 point) A convex mirror has a focal length of -5 cm. Based on the sign rules of the convex mirror, this equation can be changed to the equation of the concave mirror, if the image distance (di) is given a negative sign because the beam of light does not pass the image and focal length (f) is also given a negative sign because the focal point of the convex mirror is not passed by light (see the figure of the image formation above). Find the location of the image. The distance between the object and the convex mirror is measured at the point where the image reflection reaches an approximate size of the object. The minus sign indicates that the focal point is virtual. If the image is real give a positive answer and a virtual image should be a negative answer. As a result, the image formed by these mirrors cannot be projected on the screen as the image is inside the mirror. Code to add this calci to your website .
