1. The wave velocity (v), the wavelength (λ), and frequency (f) are related by the equation: v = fλ where: - v, the wave velocity, is measured in meters per second (m/s), - f , the frequency, is measured in hertz (Hz) - λ, the wavelength, is measured in meters (m). This equation proves that the speed oRead more

    The wave velocity (v), the wavelength (λ), and frequency (f) are related by the equation:
    v = fλ
    where:

    – v, the wave velocity, is measured in meters per second (m/s),
    – f , the frequency, is measured in hertz (Hz)
    – λ, the wavelength, is measured in meters (m).

    This equation proves that the speed of a wave is the product of its frequency and wavelength.

    A mechanical wave needs a medium (air, water, or solids) in which to propagate. Since it travels along compressions and rarefactions in a medium, sound waves are mechanical waves.

    Light waves, radio waves, and X-rays are electromagnetic waves, unrelated to a medium and certainly able to travel through a vacuum.

  3. A regular hexagon has 6 equal sides. The perimeter (P) of a hexagon is given by: P = 6 × side length Given that P = 24 cm, we solve for the side length: side length = 24 cm / 6 = 4 cm Thus, each side of the hexagon is 4 cm.

    A regular hexagon has 6 equal sides. The perimeter (P) of a hexagon is given by:

    P = 6 × side length
    Given that P = 24 cm, we solve for the side length:
    side length = 24 cm / 6 = 4 cm
    Thus, each side of the hexagon is 4 cm.
