I agree with your answer. The actual answer given must be a mistake
A transverse wave is a type of wave in which the particles of the medium vibrate perpendicular to the direction of wave propagation. This is in contrast to a longitudinal wave, in which the particles vibrate parallel to the direction of wave propagation. Examples of transverse waves include light, electromagnetic waves, and water waves.
One common problem with transverse waves is dispersion, which is the spreading out of different frequencies of the wave due to differences in their speeds. Another problem is reflection, which occurs when a transverse wave hits a boundary and bounces back in the opposite direction. Transverse waves can also experience refraction, which is a change in direction and speed when passing through different mediums.
The speed of a transverse wave can be calculated by multiplying the frequency of the wave by its wavelength. This equation is represented as v = fλ, where v is the speed, f is the frequency, and λ is the wavelength. The speed of a transverse wave can also be affected by the properties of the medium it is traveling through, such as density and elasticity.
Transverse waves have many real-world applications, including communication systems such as radio and television broadcasting, as well as wireless technologies like Wi-Fi and Bluetooth. Transverse waves are also used in medical imaging techniques such as X-rays and MRI scans. They are also important in engineering processes, such as ultrasonic testing, which uses transverse waves to detect flaws in materials.
The amplitude of a transverse wave is directly proportional to its energy. This means that as the amplitude increases, so does the energy of the wave. This can be seen in everyday examples, such as when a larger ocean wave carries more energy than a smaller one. In terms of mathematical equations, the energy of a transverse wave is equal to the square of its amplitude, so doubling the amplitude will result in four times the energy.
