Extended Spectrum Beta Lactamase Extended Spectrum Beta-Lactamase (ESBL) is an enzyme made by some bacteria. The enzyme prevents certain antibiotics from being able to kill the bacteria. The bacteria then become resistant to the antibiotics. This means stronger antibiotics must be used to kill the bacteria. ESBL infections usually occur in the urinary tract, lungs, skin, blood, or abdomen.

Frequency vs. Wavelength The relationship between a radio signal's frequency and its wavelength can be found by the following formula: wavelength = 300 / frequency in MHz. According to this formula, a frequency of 9680 kHz would be equivalent to a wavelength of 30.99 meters, which we would round to 31 meters. Thus, 9680 kHz, 9.68 MHz, and 31 meters all refer to the same operating frequency! As the formula indicates, the wavelength of a radio signal decreases as its frequency increases.

How can I calculate the wavelength of radio waves? To calculate the wavelength of a radio wave, you will be using the equation: Speed of a wave = wavelength X frequency. Since radio waves are electromagnetic waves and travel at 2.997 X #10^8# meters/second, then you will need to know the frequency of the radio wave. If the radio wave is on an FM station, these are in Megahertz. A megahertz is one million hertz.

Wavelength in meters problem. Thanks!? What is the wavelength (in meters) of photons with the following energy? 92.5 kJ/mol I tried this myself but I didn't get it right. I'm using an online hw tutorial, and I can't seem to get this one right.ubstituting in the above equation we get: wavelength = [(6.63 × 10^−34 J∙s)(3.00 x 10^8 m/s)] / (1.54 x 10^-19 J) = 1.29 x 10^-6 m.

For radio waves and other wireless signals as w … ell as the speed a signal travels along a wire, the speed of the wave is approximately 299,792,458 meters per second (the speed of light).he speed of a wave equals the frequency times the wavelength (speed = frequency x wavelength). Therefore, the wavelength would equal the speed divided by the frequency. Also, … the speed of a wave in a vacuum is the speed of light, c, which is a constant.

What Is The Rydberg Formula? The Rydberg formula is a mathematical formula used to predict the wavelength of light resulting from an electron moving between energy levels of an atom. Answer: When an electron changes from one atomic orbital to another, the electron's energy changes.hen the electron moves from low energy to a higher energy state, a photon of light is absorbed by the atom. Each element has a distinct spectral fingerprint.
