Question 1:

Medium

In a room with natural lighting, a student uses a flat mirror to observe the reactions in an optics experiment. At a distance of 3 meters from the mirror, an object 10 cm in height is placed perpendicularly to the mirror. Based on your knowledge of image formation in flat mirrors, analyze and justify: a) What will be the height of the image reflected by the mirror. b) If the student moves to a position where they are 2 meters from the mirror, how will this affect the position and size of the image in relation to the observer?

Question 3:

Medium

In an optics laboratory, a beam of light strikes perpendicularly on a flat mirror and generates a reflection that hits another object, located at a distance of 2 meters from the mirror. A student, while analyzing the phenomenon, observes that the image formed in the mirror is at the same distance from the object in relation to the mirror. Considering the situation described and the properties of reflection in a flat mirror, answer the following items: 1) Explain why the image observed by the student is at a distance equal to that of the object in relation to the mirror, and not at a shorter distance, as could occur in other types of mirrors. 2) If the mirror were moved to a new position, so that the distance from the object to the mirror was reduced to 1 meter, describe how the position and characteristics of the image formed in the mirror would be affected.

Question 5:

Medium

Consider a beam of monochromatic light incident on a flat mirror in such a way that the angle of incidence is 30 degrees. This beam strikes the mirror from a point P at a height of 1.5 meters above a table, forming a reflection angle of 30 degrees. Upon reflection, part of this beam strikes a ruler placed perpendicularly to the mirror's surface, creating a line of reflected light that reaches a point Q at a distance of 2 meters from the point of incidence on the mirror. Based on this setup, answer: (1) Calculate the perpendicular distance from the point of incidence P to the point where the line of light strikes the ruler, knowing that the height of point Q above the table is 1 meter. (2) Analyze the result obtained in light of the concept of image formation in flat mirrors and explain how the property that the distance from the mirror to the image is equal to the distance from the mirror to the object is reflected in your solution.
