a 26 cm object is 18 cm in front of a plane mirror. a ray of light strikes the object and is reflected off the mirror at a 42 - degree angle. what is the angle of reflection? degrees what type of image is formed? what is the size of the image? cm
Answer
Explanation:
Step1: Recall law of reflection
According to the law of reflection, the angle of incidence is equal to the angle of reflection. Given the angle of reflection is measured as 42 - degree when light is reflected off the mirror, so the angle of reflection is 42 degrees.
Step2: Determine image type
For a plane - mirror, the image formed is virtual. This is because the light rays do not actually converge at the location of the image but appear to diverge from that point.
Step3: Find image size
In a plane - mirror, the size of the image is the same as the size of the object. The object is 26 cm, so the size of the image is also 26 cm.
Answer:
42 degrees Virtual 26 cm
