WebThe hearing frequency range for all healthy humans is 20Hz – 20 kHz. Some people’s hearing range may vary by 10Hz or so, but it is a general rule that humans hear between 20 Hz and 20 kHz. Animal hearing spectrums are similar to ours and then some. Whales, for example, can hear below 10Hz, bats can hear up to 100 000 Hz, a dog up to 46 000 Hz etc. The types of electromagnetic radiation are broadly classified into the following classes (regions, bands or types): Gamma radiationX-ray radiationUltraviolet radiationVisible lightInfrared radiationMicrowave radiationRadio waves This classification goes in the increasing order of wavelength, which is … See more The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.
