Which equation should be used to calculate the speed of a wave? speed = frequency x wavelength speed = frequency x hertz speed = period x wavelength speed = period x hertz

speed = frequency x wavelength

Explanation:  The speed of a wave is given by the product of its frequency and wavelength.

Frequency can be defined as the number of oscillations in a unit time. Its unit is hertz or s⁻¹.

wavelength can be defined as the distance between two crests or two troughs. Its unit is m.

Thus, the speed of wave is given as:

speed (ms⁻¹) = frequency (s⁻¹) × wavelength (m)

the answer would be 32*f

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
