Wavelength

The tubes have a wavelength of 0.658m. 2. Using your calculated wavelength, and the speed of sound = 345 m/s, calculate the frequency of your tuning fork. 345=f*.658 The calculated frequency of the tuning fork is 524 Hz. 3. The accepted frequency of the tuning fork is was printed on your fork. Using the accepted frequency, calculate the %error for both measurements. The percent of error of the frequency of the tuning fork is 2.34%, and the percent error for the wavelength is 1.79%. Discussion

technologies. FSO provides the transmission of data with unlimited bandwidth. The atmospheric attenuation is caused by two main factors absorption and scattering. This paper investigates a performance study of free space optics channel for variable wavelengths 850 nm, 950 nm and 1550 nm at distance range of 1 km. The simulation reports minimum BER for NRZ-OOK modulation technique at different receiver diameters in presence of fog, rain and humidity attenuation. The results shows how to improve the system

ear identified the waves as light and sound. The waves of light and sound can describe in term of wavelength, frequency and amplitude. Wavelength is the distance from one peak of the wave to the next. Frequency is the number of complete waves or cycles that pass a given point amount of time. Amplitude is height of the wave from baseline to peak. These are shown in the Figure 3. The different wavelength, amplitude and frequency makes various sound and vision experience.

Ice, like other reflective surfaces, absorbs and reflects light. Different colors of light emits different wavelengths. Lighter colors of light such as red, yellow, and orange have longer wavelengths ranging from 500 nanometers to 700 nanometers. Darker colors such as blue, green, and purple have a shorter wavelength, ranging from 380 nanometers to 500 nanometers. Anything above 700 nanometers are considered infrared and anything below 380 is considered ultraviolet. Ultraviolet lights are so powerful

outphase. The first section is titled, Interference. Interference takes place between waves that have the same wavelengths. A resultant wave is formed when two waves with the same wavelength interact. The resultant wave is the consequence of the interference between two waves. With constructive interference, component waves combine and form a resultant wave with equal wavelengths, but there is

place to another then this would not be a wave. It would be translational or circular motion, but not oscillatory motion. 20.03 What does it mean if the period of a wave is .20s? It is not correct to say that this means that the wavelength is .20s. The wavelength is the distance between the crests or troughs. It is a distance not a time. It is also not correct to say that the wave continues to travel for .20s before stopping. The wave may actually continue

measure the frequency of an unmarked tuning fork. By completing the experiment in the exact same process one can determine the wavelength. Once the wavelength was determined using the temperature the speed could be calculated. Both wavelength and speed are variables in the velocity of sound formula (v = ƛf ). Using algebra, frequency could be determined by substituting wavelength and speed. The percent error for this lab could have been affected by not accurately determining the point of which the

nodes the wavelength could be measured because the distance between two nodes is a half a wavelength. The lab was conducted with standing waves because it ensures the nodes and antinodes are stationary and easy to measure. This lab would not have been possible with other types of waves that did not have stationary nodes. The

water to air (and repeat). Our hypothesis is, if we can find a object to bend the light around us then we will be able to sneak past security. Using a computer simulator, we proceeded with our experiment and took a look at the angles, the speed, the wavelength and the intensity of light. Here’s what we found.

resolution in a microscope is: R=λ/2NA where λ is the wavelength of light and NA is the numerical aperture of the objective lens. A higher value equated for R will give a poor resolution, whereas a lower value will form a more detailed resolution. A higher NA will produce a superior resolution because R will be reduced. Also, the smaller the wavelength, the lesser R will be, generating more detailed resolution. Because of this, the wavelength of blue/violet light is significantly smaller and will
