1. A single disturbance that moves from point to point through a medium is called a ___. a. period b. periodic wave c. wavelength d. pulse Answer: D A wave is a continuous and repeating disturbance of a medium and a pulse is a single disturbance. 2. If the particles of the medium are vibrating to and fro in the same direction of energy transport‚ then the wave is a ____ wave. a. longitudinal b. sound c. standing d. transverse Answer: A In longitudinal waves‚ particles of the medium

Exercise 7.1.1 Why is it impractical for an organization to own the entirety of a WAN? There are no limitations on WANs so they can be custom built for the size of the organization. Why is it favorable for an organization to maintain ownership of the entirety of the LAN? For the purpose of organizational expansion. Exercise 7.1.2 What effect will increasing the required transmission distance have on transmitting the signal clearly? The longer the distance the more chances that you

Lab 3: Hydrogen Spectrum Abstract When white light is viewed through a diffraction grating‚ we can see each component that makes up the light. However‚ when in an excited state‚ a gaseous element produces bright light of specific wavelengths rather than a continuous spectrum of colors. This phenomenon ultimately lead to the Neils Bohr model of the atom in 1913. Introduction In the middle of the 19th century‚ Robert Bunsen and Gustav Kichoff observed that gases emit spectral lines specific

PHOTODIODE * a type of photodetector capable of converting light into either current or voltage‚ depending upon the mode of operation. The common traditional solar cell used to generate electric solar power is a large area photodiode. * a semiconductor with a p-n junction PRINCIPLES OF PHOTODIODE * Photons is the source of its energy * Energy can be solved by the equation: W=hf Where: h =Planck’s constant= 6.624×10-34 f = frequency * The frequency is‚ in

Submit your completed lab report to the Lab: Photosynthesis Lab assignment link for grading. For information on how this assignment will be graded‚ please visit the Course Information sectionChlorophyll and Accessory Pigments A pigment is any substance that absorbs light. The color we see comes from the wavelengths of light that reflect. Chlorophyll‚ the green pigment common to all photosynthetic cells‚ absorbs all wavelengths of visible light except green. The green reflects back to our eyes

Jamie Milano Biology 150 Photosynthesis Homework April 8‚ 2013 Reviewing Your Knowledge 2. A pigment solution contains compound A with 4 polar groups and compound B with 2 polar groups. You plan to separate these compounds using paper chromatography with a non-polar solvent. Predict the location of the two bands relative to the solvent front. Explain your answer. Since compound A is probably more polar than compound B‚ compound B will move further in the chromatography. Since the solvent is non-polar

Waves are mainly known for their way of transferring energy from one place to another without transferring any matter.Transverse and longitudinal are waves in which can be related to one another in some kind of way. A transverse wave is a wave in which vibrates perpendicular to the direction of the waves motion. As a transverse wave travels through a medium‚ the individual particles of the medium move perpendicular to the direction of the wave travel. They may occur in a string‚ in the surface of

Light Intensity Experiment: For the light intensity experiment‚ our first set of data illustrated strange correlations between the three tubes placed in front of a light source‚ so the data provided in e-campus was used. The tube that was 24 cm away from the light had the greatest decrease in absorbance over the course of 20 minutes‚ followed by the 30 cm and then the 49 cm light apparatus. The tube that was placed in the dark (wrapped in foil) remained a dark blueish-green color whereas the tubes
