In the standing wave equation F(A, L, n, c; x, t), the speed of sound (c) determines the frequency of the emitted note. The frequency is inversely proportional to the wavelength, which is calculated as λ = 4L/(2n - 1).

Answer: d) Frequency

Explanation: The speed of sound in air is affected by temperature, humidity, and pressure, but it is not affected by the frequency of the sound wave.

The equation that describes the diffusion of heat in solid media is known as the heat equation. It constrains the evolution of temperature within the material based on the diffusion process.

The wave equation describes mechanical waves, which can include phenomena like vibrations in solids or waves propagating through a medium. It is specifically applicable to homogeneous and isotropic non-conducting solids.

In the equation F(A, L, n, c; x, t), the parameter A represents the amplitude of the wave, which corresponds to the maximum sound pressure in the bore. The amplitude is related to the loudness of the note produced by the wave.

The phase velocity is calculated as the ratio of wavelength (λ) to the period (T) of a wave.

Plasma waves combine mechanical deformations and electromagnetic fields. They are observed in ionized gases called plasmas and are significant in various natural and laboratory settings.

Answer: c) 170 Hz

Explanation: The frequency of a sound wave can be calculated by dividing the speed of sound by the wavelength. In this case, 340 m/s ÷ 1 m = 340 Hz. However, this is the frequency of a wave with a wavelength of 1 meter. To find the frequency of a wave with a different wavelength, we need to use the formula f = v/λ, where f is the frequency, v is the speed of sound, and λ is the wavelength. In this case, f = 340 m/s ÷ 2 m = 170 Hz.

The phase velocity represents the rate at which the phase of a wave propagates in space, while the group velocity measures the propagation of the overall shape of the wave's amplitudes or its envelope.

Electromagnetic waves have specific designations based on their frequencies or wavelengths. These include radio waves, infrared radiation, terahertz waves, visible light, ultraviolet radiation, X-rays, and gamma rays.
