### Slide Projector and Lens CalculationsA certain slide projector has a 118-mm focal-length lens.---#### HintsFollow the problem-solving strategy steps outlined in "Problem-Solving Strategy: Lenses" in Section 2.4 Thin Lenses. Two additional hints: 1. You are given the focal length and object distance—distance to slide—here; what equation relates these to the image distance?2. Remember the linear magnification formula.---### Questions & Steps#### a. Real or Virtual Image?To project the image of a slide onto a screen, does this lens need to form a real image or a virtual image?- Not enough information given- Virtual image- **Real image** (This option is selected)#### b. Image Distance CalculationIf a slide is placed 123 mm from the lens, how far from the lens should the screen be placed for a sharp image?Image distance: \( \_\_\_\_\_ \) mm away from lens.#### c. Dimension CalculationIf the size of the slide is 36.0 mm (width) by 24.0 mm (height), what are the dimensions of the image?Width: \( \_\_\_\_\_ \) mm; Height: \( \_\_\_\_\_ \) mm---The film should be positioned at the location of the image to record the image.---### Explanation of Graphs or DiagramsThere are no graphs or diagrams provided in the text. The table sets up a problem that must be solved using the provided information about the lens's focal length, object distance (distance to the slide), and the magnification formula.### Relevant Equations**Lens Formula:**\[ \frac{1}{f} = \frac{1}{d_o} + \frac{1}{d_i} \]Where:- \( f \) = focal length of the lens- \( d_o \) = distance to the object (slide)- \( d_i \) = distance to the image (screen)**Magnification Formula:**\[ m = \frac{h_i}{h_o} = -\frac{d_i}{d_o} \]Where:- \( m \) = magnification- \( h_i \) = height of the image- \( h_o \) = height of the object (slide)- The negative sign denotes that the real

A certain slide projector has a 118-mm-focal-length lens. Hints Follow the problem-solving strategy steps outlined in "Problem-Solving Strategy: Lenses" in Section 2.4 Thin Lenses. Two additional hints: (1) you are given the focal length and object distance-distance to slide-here; what equation relates these to the image distance? (2) Remember the linear magnification formula. a. To project the image of a slide onto a screen, does this lens need to form a real image or a virtual image? not enough information given virtual image O real image b. If a slide is placed 123 mm from the lens, how far from the lens should the screen be placed for a sharp image? mm away from lens. c. If the size of the slide is 36.0 (width) by 24.0 (height) mm, what are the dimensions of the image? Width = mm; Height = mm The film should be positioned at the location of the image to record the image.
