6) Which of the following(s)is/are correct? Electromag etic radiation is a form of energy that is transmitted through space at enormous velocities. II- Amplitude is the vertical distance from the midline of a wave to the peak. III.Wavenumber is the distance between two successive crests. A) Only III B) I and II I and III D II and III E) 1,11 and ur

The correct answer is B) I and II.<br /><br />Explanation:<br />I. Electromagnetic radiation is indeed a form of energy that is transmitted through space at enormous velocities. This includes various types of waves such as visible light, radio waves, and X-rays.<br /><br />II. Amplitude is correctly defined as the vertical distance from the midline of a wave to the peak. It represents the maximum displacement of the wave from its equilibrium position.<br /><br />III. Wavenumber is not the distance between two successive crests. Instead, it is the spatial frequency of a wave, typically measured in cycles per unit distance. The distance between two successive crests is actually the wavelength.
