Aqa Physics A Unit 2

The scientist has a double chicken feed of known separation. Describe the measurements that neediness to be taken and explain how they atomic number 18 used to let the wavelength of the light. treat any necessary golosh precautions and how you would arrange the frame-up to mend accuracy. Measurements * w thrifty with vernier scale calliper * D measured with a meter rule decision the wavelength * Use ?=wsD to get pass judgment for ? Accuracy * Several fringe spaces measured * Centres of fringes used * louvre or much fringes measured * prodigious value for D * D greater or partake to 2m * colored room * Repeat measurements Safety * Avoid shing optical maser at a person * laser safety goggles * Avoid reflections * word of advice sign or light human body 4 shows a unmoving wave on a string. The string is tied onto a thin admixture kibosh at A and decided at B. A frisson generator causes the bar to vary at a chosen frequency. Explain how a unmoving wave is formed. because describe the refer features of the stationary wave shown in Figure 4.

* Waves reflect dispatch the clamp and the rod * Waves travelling in opponent directions superpose * Waves have same(p) wavelength and frequency, similar bounteousness * Always cancellation at leaf nodes and creative super set up at antinodes * Energy is not transferred on string * 4 nodes where there is zero(a) amplitude * 3 antinodes where amplitude is maximum * Wavelength 0.80m * final stage antinodes in phase and shopping centre and ends in antiphase * Between node and antinode, amplitude of oscillation increases On her next jump the gymnast decides to urinate a height supra shoes B. Describe and explain, in scathe of animation and work, the transformations that progress as she ascends from her lowest position A until she reaches her new position above B. * Elastic latent energy is alter to energising energy * Kinetic energy is transformed into gravitative potential energy * The gymnast must use...If you want to get a extensive essay, order it on our website: Ordercustompaper.com
