Could you tell me which textbook this question is from?? And the answer if you got from other sourcesRajanjx786 said:
The frequency of emitted radiation refers to the number of oscillations or cycles of the electromagnetic wave per second. It is measured in Hertz (Hz) and can range from extremely low frequencies (ELF) to extremely high frequencies (EHF).
The frequency of emitted radiation is determined by the source of the radiation, such as an atom or molecule, and its energy level. Each type of radiation, such as radio waves, microwaves, or X-rays, has a specific range of frequencies that it can emit.
High frequency radiation, such as X-rays and gamma rays, can have harmful effects on living organisms due to their high energy. They can cause damage to cells and DNA, leading to health problems such as cancer. It is important to limit exposure to high frequency radiation.
The frequency of emitted radiation is determined by the source and cannot be changed. However, certain materials and devices can alter the frequency of radiation, such as lenses in telescopes or filters in cameras.
The frequency and wavelength of emitted radiation are inversely proportional. This means that as the frequency increases, the wavelength decreases, and vice versa. This relationship is described by the equation: wavelength = speed of light / frequency.
