#tag_title# Step 3: Calculate the image distance (d_i) #tag_content#Using the lens formula, we can find the image distance: \(\frac{1}{d_i} = \frac{1}{12} - \frac{1}{10}\) Now, we calculate the common denominator and subtract the fractions: \(\frac{1}{d_i} = \frac{10 - 12}{120}\) \(\frac{1}{d_i} = -\frac{2}{120}\) Now, we take the reciprocal to find d_i: \(d_i = -60\) cm The negative sign indicates that the image is on the same side of the lens as the object, which means it is a virtual image. #tag_title# Step 4: Calculate the magnification #tag_content#Magnification (m) is given by the ratio of the image distance to the object distance: \(m = \frac{d_i}{d_o}\) Using the given values, we can calculate the magnification: \(m = \frac{-60}{10}\) \(m = -6\) The negative magnification indicates that the image is inverted relative to the object. #tag_title# Step 5: Calculate the image height #tag_content#Now, we can find the image height (h_i) using the magnification: \(h_i = m \times h_o\) We already know the magnification and object height: \(h_i = -6 \times 5.00\) mm \(h_i = -30.0\) mm The image is 30.0 mm tall and inverted. #tag_title# Step 6: Determine the properties of the image #tag_content#The image properties can be summarized as follows: - Position: The image is 60 cm from the lens on the same side as the object (virtual image). - Magnification: The image is 6 times larger than the object (magnification of -6). - Orientation: The image is inverted, as indicated by the negative magnification. - Size: The image height is 30.0 mm. #tag_title# Step 7: Calculate the angular magnification #tag_content#Angular magnification (M) is given by the ratio of the image size to the object size: \(M = -m\) Using the magnification we obtained earlier: \(M = -(-6)\) \(M = 6\) Therefore, the angular magnification is 6. #tag_title# Short Answer #tag_content#The image of the insect is 60 cm away on the same side of the lens as the object, forming a virtual image. The image is 30.0 mm tall, which is 6 times larger than the object, and it is inverted. The angular magnification is 6.

Step by step solution

01

Understand the given information

We are given the following information: - Object distance (d_o) = 10.0 cm - Focal length (f) = 12.0 cm - Object height (h_o) = 5.00 mm
02

Use the lens formula to find image distance

The lens formula is given by: \(\frac{1}{f} = \frac{1}{d_o} + \frac{1}{d_i}\) We know the focal length (f) and object distance (d_o), so we can solve for the image distance (d_i): \(\frac{1}{d_i} = \frac{1}{f} - \frac{1}{d_o}\)

A dissecting microscope is designed to have a large distance between the object and the objective lens. Suppose the focal length of the objective of a dissecting microscope is \(5.0 \mathrm{cm},\) the focal length of the eyepiece is \(4.0 \mathrm{cm},\) and the distance between the lenses is $32.0 \mathrm{cm} .$ (a) What is the distance between the object and the objective lens? (b) What is the angular magnification?
Comprehensive Problems Good lenses used in cameras and other optical devices are actually compound lenses, made of five or more lenses put together to minimize distortions, including chromatic aberration. Suppose a converging lens with a focal length of \(4.00 \mathrm{cm}\) is placed right next to a diverging lens with focal length of \(-20.0 \mathrm{cm} .\) An object is placed \(2.50 \mathrm{m}\) to the left of this combination. (a) Where will the image be located? (b) Is the image real or virtual?
A nearsighted man cannot clearly see objects more than \(2.0 \mathrm{m}\) away. The distance from the lens of the eye to the retina is \(2.0 \mathrm{cm},\) and the eye's power of accommodation is \(4.0 \mathrm{D}\) (the focal length of the cornea-lens system increases by a maximum of \(4.0 \mathrm{D}\) over its relaxed focal length when accommodating for nearby objects). (a) As an amateur optometrist, what corrective eyeglass lenses would you prescribe to enable him to clearly see distant objects? Assume the corrective lenses are $2.0 \mathrm{cm}$ from the eyes. (b) Find the nearest object he can see clearly with and without his glasses.
A refracting telescope is used to view the Moon. The focal lengths of the objective and eyepiece are \(+2.40 \mathrm{m}\) and \(+16.0 \mathrm{cm},\) respectively. (a) What should be the distance between the lenses? (b) What is the diameter of the image produced by the objective? (c) What is the angular magnification?
The eyepiece of a microscope has a focal length of \(1.25 \mathrm{cm}\) and the objective lens focal length is \(1.44 \mathrm{cm} .\) (a) If the tube length is \(18.0 \mathrm{cm},\) what is the angular magnification of the microscope? (b) What objective focal length would be required to double this magnification?
