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

our eye stretched a rolling terrain covered by light green moss. We remain a little anxious‚ as the sky still cloudy. Finally we reached the top and proceeded on foot up a slope about one hundred meters. As we approached the crater‚ someone was standing on the tip waving his hand excitedly and shouting for us to climb quickly. Encouraged by him‚ we climb as quickly as we could in spite of the fact that the slope was composed of powdered lava. Upon arriving our destination‚ we stood there in a awe

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

You can wave your hands wave left hand during left turn and right hand during right turn. You can use the light signal its better to use the hand signal during morning time that too during bright day light. If you halt at the signal you must wave the right hand that you cannot move still more in the right as the movement will take you to the opposite side of the road. If you
