Witryna1 sty 1997 · Today's SDH radio technology is capable of delivering bandwidth efficiencies of over 8 bps for every hertz of bandwidth (8 bps/Hz). In particular, 512-state quadrature amplitude modulation (QAM) technology packs two STM-1s in a single 40 MHz channel using a single carrier. WitrynaThis is half the wavelength of a microwave. Look for a sticker on your microwave that tells you its frequency in Hertz (Hz). Most microwaves are around 2450 MHz. Note: MHz = 10^6 Hz. Use the following equation to find the speed of light: Speed of light = 2 x (distance between melted spots) x (frequency of microwave) The actual speed of …

Witryna3 maj 2024 · Household microwave ovens operate at 2.45 GHz, apparently. So the energy of a photons is E = h f = 6.63 × 10 − 34 × 2.45 × 10 9 = 1.62 × 10 − 24 Joules. So if you take an 800 Watt unit, that is putting 4.92 × 10 26 photons per second into the microwave unit. Which is indeed `many photons'.
