Wave interference - Simulation

By Sandile MHlophe -
  Topics Interference Double Slit Diffraction Waves Description Make waves with a dripping faucet, audio speaker, or laser! Add a second source to create an interference pattern. Put up a barrier to explore single-slit diffraction and double-slit interference. Experiment with diffraction through elliptical, rectangular, or irregular apertures. Sample Learning Goals Make waves with water, sound, and light and see how they are related. Design an experiment to measure the speed of the wave. Create an interference pattern with two sources, and determine the ways to change the pattern. Find points of constructive and destructive interference by eye and by using the detectors. Put up a barrier to see how the waves move through one or two slits. What sort of pattern do the slits create? How can you change this pattern? For light, predict the locations of the fringes that appear on the screen using d sin(θ) = mλ. Use the tape measure to verify your predictions. Explain how the aperture geo...

UBHUKU LWAMANQE – EJ Mhlanga

By Sandile MHlophe -
 Umlingiswa ongummeleli emdlaweni othi, Ubhuku lwamanqe. ISINGENISO  Ummeleli ngumlingiswa oyiqhawe. Indaba yonke incike kuye.  Yize engekho kwezinye izehlakalo kodwa ziyamthinta ngandlela thize. Indaba yonke imayelana naye. Ubhekana nenkinga ethile ashikashikeke ezama ukuyixazulula. Kuyenzeka aphumelele noma ehluleke.

Why liminal spaces are uncertain and ambiguous

By Sandile MHlophe -
Why liminal spaces are uncertain and ambiguous and promote a feeling of communitas amongst the people who occupy these spaces.  Posted by  Sikhanyisiwe Mkhonto We are constantly moving from one space to another. These are often large socially constructed spaces that create meanings or serve a function in our society. There are however spaces where we are neither in nor out. This space is the centre of two large spaces. A small space where one feels connected with the fellow members who are occupying that small space in that moment (Shortt, 2015: 634). Turner investigated the works of Arnold Van Gepp who spoke of the concept of ‘rite de passage.’ Victor Turner’s focus was the liminal period of a ritual. ‘Liminality is ambiguous, this is because the individual is not being classified into any category which confirms their role in a cultural society’ (Turner, 1969: 95). In this liminal period members involved experience a sense of harmony, this is what Turner labels as communit...

BENGITHI LIZOKUNA – NG Sibiya

By Sandile MHlophe -
 BENGITHI LIZOKUNA – NG Sibiya Umbuzo: Xoxa ngempumelelo yombhali ekudluliseni umyalezo othi: 'Izinqumo esizithathayo ngempilo yethu zingaba nemiphumela engemihle empilweni yethu neyabanye abantu' ubhekise kulaba balingiswa: uMhlengi/Mahlengi, uNontobeko, uXolani, noNgidi kule noveli ethi, Bengithi Lizokuna. ISINGENISO Umyalezo yilokho umbhali asixwayisa noma aseluleka ngakho enovelini/yisifundo esitholakala uma sifunda inoveli. Umyalezo uchaza ukuthi umbhali ubehlose ukusazisani ngokubhala le ndaba. Umyalezo wale noveli umayelana nokuthi izinqumo esizithathayo ngempilo yethu zingaba nemiphumela engemihle kwabanye abantu nakithina uqobo. Ohlolwayo angasebenzisa la maphuzu alandelayo namanye amayelana nomyalezo kule noveli.

IMPI YABOMDABU ISETHUNJINI – JC Buthelezi

By Sandile MHlophe -
 ISINGENISO  Umyalezo yilokho umbhali asixwayisa noma aseluleka ngakho enovelini/yisifundo esitholakala uma sifunda inoveli. Umyalezo uchaza ukuthi umbhali ubehlose ukusazisani ngokubhala le ndaba. Umyalezo wale noveli uthi: Ukungawazisi umndeni wakho kuba nemiphumela engemihle empilweni yakho. UMZIMBA  UBafana  Ukuba yisifundiswa kukaBafana kwenza ukuba uBafana awubukele phansi/angawazisi umndeni wakhe. La maphuzu alandelayo akhombisa izinto ezenziwa uBafana ukungawunakekeli umndeni wakhe:  • UBafana uxosha umalume wakhe kabuhlungu uma ezocelela izingane zikaLinono indawo yokuhlala.  • Ukungazwani kukaBafana noPoppie kwenza u-Euthenasia eqe ekhaya.  • UBafana akanasikhathi sezingane zakhe.  • UBafana uba nomona ngokuzithuthukisa kukaPoppie ngokufunda umtshela nokuthi akayeke ukufunda.  • Ukuhluleka kukaBafana ukubhekana nezinkinga zasemzini wakhe kwamenza walifulathela ikhaya. Umphumela wokungawazisi umndeni empilweni kaBafana: • Udlala izin...

Gas Properties - Simulation

By Sandile MHlophe -
  Topics Ideal Gas Law Kinetic Molecular Theory Diffusion PV Work Maxwell-Boltzmann Distribution Description Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other. Examine kinetic energy and speed histograms for light and heavy particles. Explore diffusion and determine how concentration, temperature, mass, and radius affect the rate of diffusion. Sample Learning Goals Determine how changing a variable among P, V, N, and T influences other gas properties. Describe the relationship between particle-wall collisions and pressure. Predict how changing temperature will affect the speed of molecules. Predict the speed of molecules in thermal equilibrium based on the relative masses of molecules. Identify when pressure-volume work is done on ...

Do we have free-will?

By Sandile MHlophe -
 Are you free?  we often think we are free but are we really free? this question sounds so simple yet it is actually not. What does it even mean to be free? Well in this post I will explain to the best of my knowledge what is free will and whether we have it or not. can you escape fate? Let's consider the story below: When Thabiso was born a prophet foretold that he would grow up to kill his father and then marry his mother. His father fearing for his life decided to leave the baby in the wilderness with the hope that he will die, thefore the prophecy will not come  true. The baby was found by another couple, and grew up knowing them as his parents. The boy heard of the prophecy, not knowing his adopted and because he loves his father(adopted) he decided to go away from his family to avoid the prophecy. In the way he met and killed a man and then felt bad for the wife of this man, he decided to marry her. The man he met is in fact his fat...
