140 Standing Wave Odd Harmonics. November 7, 2016. This video shows the standing waves that can be formed on a string that is fixed at one end or loose at the other end. Any standing wave that forms on this string must have a node at the fixed end, and antinode at the loose end. The simplest standing wave fulfills these conditions is the NA. (Node-Antinode) The next standing wave that can be formed is the NANA, followed by. NANANANANA, and so on. NA’s wavelength is called the fundamental wavelength,.

1001 Wall of Death. October 15, 2016. If done on a horizontal surface, it would be the normal contact force holding up the weight of the bike, and the frictional force providing the required centripetal force. When done on a vertical surface (as in this video), it is the frictional force holding up the weight of the bike, and the normal contact force providing the required centripetal force.

014 What is the air pressure in the bottle? March 13, 2014. It’s all about the pressure of the air in the bottle, P. If not water will not be squirting out of the bottom hole. If not air will not be sucked through the upper holes. Putting the two inequalities together, we get. Basically, as water drains from the bottom hole, P. Drops due to expansion of the air pocket, drawing air into the bottle through the upper holes. This top up of air molecules to the air space increases P. March 11, 2014. Let’...

138 Wave Reflection | xmdemo
https://xmdemo.wordpress.com/2016/11/07/138
November 7, 2016. In this video, a wave pulse is sent down the spring. When the pulse reaches the end of the spring, it is reflected back. (In technical jargon, we say that the end of the spring represents a discontinuity in the medium. There is always a reflection when a wave arrives at a medium boundary). If the end of the spring is fixed, the pulse returns on the other side of the spring. In technical jargon, we say the wave undergoes a 180 phase change if the boundary is hard ). 40 W vs 60 lessoni&he...

139 Standing Wave Harmonics. November 7, 2016. This video shows the standing waves that can be formed on a string fixed at both ends. Since the string is fixed at both ends, any standing wave that forms on the string must have nodes at both ends. The simplest standing wave that has nodes at both ends is the NAN. (Node-Antinode-Node) The next standing wave that can be formed is the NANAN, followed by. NANANANANAN, and so on. Notice that each NAN corresponds to one half-wavelength segment. This means.

October 15, 2016. When we see the bodies pinned against the wall, it is tempting to imagine that there are some centrifugal forces pushing those people outward against the wall. But there is none. Those people are moving in circles, which required a centripetal force. The normal contact force that the wall exerted on the bodies provided this required centripetal force. The motion is fully explained by the presence of a. Not a centrifugal force. Let’s banish the centrifugal force forever.

October 15, 2016. Surely you noticed that the track was slanted at the bends? These are called banked curves. If you had watched F1 racing before, you should know that F1 race tracks are flat. The race cars have to slow down (F1 fans love to watch and hear the acceleration) when they go into the curves . If they do not, the required centripetal force (. Will be too large. The tires just do not have enough grip to produce the required amount of friction. Worked example explained at xmtutor). 066 Standing ...

137 Lissajous Figures on CRO. September 6, 2016. When the CRO is set to the. Mode, it uses the Channel 1 input as the time-base. This means the. Position of the CRO trace is controlled by inputs from Channel 1 and 2 respectively. If both channels are fed with sinusoids with the same frequency, then the following traces wil result, depending on the phase relationship between the two sinusoids. In-phase. Much like the relationship between force and acceleration. 136 Ball tied to String in Circular Motion.

All posts by mrchuakh. March 8, 2017. 146 Birefringent Scotch Tape Art. March 7, 2017. Scotch tapes are birefringent. We can see them as retardation plates. Since the phase difference. Caused by the scotch tape’s birefringence Δ. Is dependent on the wavelength of the light. Different wavelength of light are “retarded” differently. This means that each wavelength of light become polarised differently. Seen through a second (crossed) polariser, white light is turned into a color light. March 7, 2017. A qua...
