- DIRECTION: 1) ILLUSTRATE THE SPECTROPHOTOMETRIC WORKFLOW PROCESS STARTING FROM THE LIGHT SOURCE UP TO THE READ-OUT DEVICE. MAKE SURE TO LABE COMPLETELY.While viewing an object under low power you see a small organism at the edge of the field of vision. You move to the high-power lens, but the organism is no longer visible. What has occurred? How do you correct it?The lens closest to the specimen is called the______________.
- Figure Q9–2 shows a diagram of the human eye. Therefractive indices of the components in the light path are:cornea 1.38, aqueous humor 1.33, crystalline lens 1.41, andvitreous humor 1.38. Where does the main refraction—themain focusing—occur? What role do you suppose the lensplays?The human eye is much like a camera—yet, when a camerashutter is left open and the camera is moved, the image willbe blurred. But when you move your head with your eyesopen, you still see clearly. ExplainBenjamin injured one of his eyes and needs to wear an eye patch over it for the next 6 weeks. He finds it difficult to reach out and grab things, such as the buttons on his shirt, because with the use of only one eye he lacks the depth cue of ______.a) relative sizeb) occlusionc) binocular disparityd) linear perspective
- Objective lens X has a limit of resolution equal to 0.2 mm while objective lens Y has 30 µm. a. Which among the two can magnify a mosquito wing in finer detail? b. Which among the two would show a greater area of the mosquito wing?Figure 36.18 Which of the following statements about the human eye is false? Rods detect color, while cones detect only shades of gray. When light enters the retina, it passes the ganglion cells and bipolar cells before reaching photoreceptors at the rear of the eye. The iris adjusts the amount of light coming into the eye. The cornea is a protective layer on the front of the eye.Watch this video (http://openstaxcollege.org/l/2point) to see a quick demonstration of two-point discrimination. Touching a specialized caliper to the surface of the skin will measure the distance between two points that are perceived as distinct stimuli versus a single stimulus. The patient keeps their eyes closed while the examiner switches between using both points of the caliper or just one. The patient then must indicate whether one or two stimuli are in contact with the skin. Why is the distance between the caliper points closer on the fingertips as opposed to the palm of the hand? And what do you think the distance would be on the arm, or the shoulder?
