    Properties of waves:

    Amplitude – Wave is an energy transport phenomenon. Amplitude is the height of the wave,
    usually measured in metres. It is directly related to the amount of energy carried by a wave.

    Wavelength – The distance between identical points in the adjacent cycles of crests of a wave is
    called a wavelength. It is also measured in metres.

    Period – The period of a wave is the time for a particle on a medium to make one complete
    vibrational cycle. As the period is time, hence is measured in units of time such as seconds or
    minutes.

    Frequency – Frequency of a wave is the number of waves passing a point in a certain time. The
    unit of frequency is hertz (Hz) which is equal to one wave per second.

    The period is the reciprocal of the frequency and vice versa.

    Q-1 : What is a wave?
    A wave is a disturbance in a medium that carries energy without a net movement of particles. It
    may take the form of elastic deformation, a variation of pressure, electric or magnetic intensity,
    electric potential, or temperature.

    Q-2: Define frequency of a wave.


    Frequency of a wave is the number of waves passing a point in a certain time. The unit of
    frequency is hertz (Hz) which is equal to one wave per second.

    Q-3: Define amplitude of a wave.


    Amplitude is the maximum displacement from the neutral position. This represents the energy of
    the wave. Greater amplitude carries greater energy.

    Q-4: What are electromagnetic waves?


    Electromagnetic waves are the disturbance that does not need any object medium for propagation
    and can easily travel through the vacuum. They are produced due to various magnetic and
    electric fields.

    Q-5: Give some examples of electromagnetic waves.


    Radio signals, light rays, x-rays, and cosmic rays are some of the examples of
    electromagnetic waves.
