Waves Introduction For this experiment‚ the use of equipment such as oscillators and function generators were used in order to calculate forms of AC waves. Waves are visual representations of the variation of a voltage or current over time and are used in many applications throughout technology. Aim The aim of this laboratory was to be able to measure the voltage in a circuit over a specific time using equipment such as an oscilloscope‚ and using it to look at the SINE wave that is

result of the difference between the phase velocity of propagation of an electromagnetic wave in air and that in the lens material. Lens antennas are used in radar and metering equipment that operates in the centimeter wavelength range. A lens antenna consists of a lens proper and of a feed. The shape of the lens depends on the refractive index n (the ratio of the phase velocity of propagation of a radio wave in a vacuum to that in the lens). A decelerating lens antenna‚ as in optics‚ is one for

The Henri Rose heaved‚ mighty waves crashing on the decks. The lantern fluttered and clicked. Sailors shouted to each other as they tightened the sails‚ checking the bindings. Some held to the sails while others tried to sit down in the inner decks of the ship. Clouds enveloped the sky. Hawkins spun the helm‚ turning the ship sideways. Thunder wrecked the mighty waves‚ emitting flashes of lightning‚ clear and crystal white‚ punching through the dark skies. Wave after wave rocked the ship‚ each larger

Sounds are waves that we hear and are caused by vibrations that travel through mediums. Depending on the medium and temperature‚ the time it takes for sound waves to travel vary. The hypothesis states that if the temperature in the air increases‚ then the speed of sound will also increase because faster-moving particles transfer energy quickly. The data collected supports the hypothesis. Therefore‚ increased air temperature affects the speed of sound because the molecules move faster‚ which causes

it. My feet find the bottom and I thrust myself upwards‚ breaking the surface and gulp the air. It’s so dark that I can’t see the jetty‚ even though it must be bare metres away from me. I can’t see which direction the waves are coming from. As I look around wildly‚ yet another wave breaks on top of me. I’m pushed even deeper under this time. It’s hard to describe‚ the feeling of breathlessness and hysteria that comes with being trapped underwater. No light. No sound. No air. My feet are pulled over

The Effect of Different Genres of Music on the Growth Rate of Garden Cress AIM The purpose of this experiment is to explore upon the possible correlation between musical stimulus and the growth rate of Lepidium sativum‚ commonly known as Garden Cress. It also aims to discover which genre amongst classical‚ jazz‚ and rock has the most beneficial effect on its growth rate. PERSONAL ENGAGEMENT The Garden Cress plant‚ better known by its botanical name Lepidium sativum‚ is amongst the many plants that

communication‚ that starts by touching (Touch) leading to various actions (ACTON).RED is used to convey the meaning of warmth in communication. Red Tacton takes a different technical approach. Instead of relying on electromagnetic waves or light waves to carry data‚ a Red Tacton transmitter couples with extremely weak electric fields on the surface of the body. The weak electric fields pass through the body to a Red Tacton receiver‚ where the weak electric field affects the optical properties
