Which describes an image that a plane mirror can make? a. the image is always real. b. the image can be either virtual or real. c. the image is never right-side up. d. the image can only be the same size as the object.

B. The image can be either virtual or real.

Explanation:

A plane mirror is one in which the reflection surface is completely flat and generates an image that can be real or virtual. Plane mirrors have a wide range of uses, from home to mirror as components of sophisticated optical instruments.

To determine the image in a plane mirror, just imagine that the observer sees an object that appears to be behind the mirror. This is because the extension of the reflected ray passes through a virtual image point (PIV) "behind" the mirror.

In plane mirrors, the object and its image always have opposite natures, that is, when one is real the other must be virtual. Therefore, to obtain the image of a point object geometrically, it is enough to draw a straight line through it and symmetrically mark the image point.

c)as speed changes, wavelength and frequency change.

everything changes!

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
