Explanation The process by which the light bends on entering a medium that is denser is typically termed as refraction. The speed of the light in a denser medium tends to decrease due to which the bending of light is made possible. If the angle between the direction of the light rays and the surface of the substance is other than 90 degrees, the light tends to refract...

Chapter 15.3, Problem 18AYP

Summary Introduction

To analyze:

The cause of the refraction of the light. The meaning of focal point and emmetropia.

Introduction:

Refraction of light is the phenomenon by which the path of the light tends to change on the change in the density of the medium in which it travels. For example, the light traveling from air into a denser medium tends to bend if it enters a medium that is denser than air.

Students have asked these similar questions

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
