Answer:

B. It decreases proportionally to the wavelength

Explanation:

The relationship between wavelength, velocity, and frequency of a wave is given as;

$f = \frac{v}{\lambda}$

where;

f is the frequency of the wave

v is the velocity of the wave

λ is the wavelength

From the equation above, the frequency of a wave is inversely proportional to its wavelength. As the wavelength increases, the frequency decreases and vice versa.

Therefore, the correct option is "B"

Heinrich hertz used properties of which type of wave to support the idea that light is also made of waves?.

Vsevolod [243]

Answer:

Hertz extended Maxwell's idea that light is produced by the interaction of electromagnetic fields. Waves produced a diffraction pattern. Results supported the wave theory of light.

Two identical loudspeakers that are 5.00 m apart and face toward each other are driven in phase by the same oscillator at a freq

Lunna [17]

Answer:0.0982 m

Explanation:

Given

distance between two loudspeaker is 5 m

frequency (f )=875 Hz

speed of sound (v)=344 m/s

Let $x_0$ be the smallest distance moved by observer then

Position of observer w.r.t to first speaker is

$x_1=\frac{L}{2}-x_0$

Position of observer w.r.t to second speaker is

$x_2=\frac{L}{2}+x_0$

$\Delta x=2x_0$

For Destructive interference

$\Delta x=\left ( m+\frac{1}{2}\right )\cdot lambda$

For minimum m=0

and $\lambda =\frac{v}{f}$

$2x_0=\frac{v}{2f}$

$x_0=\frac{v}{4f}=\frac{344}{4\times 875}=0.0983 m$

Which of the following is not an example of convection? Warm air rising from heated pavement The rolling motion of boiling water

Romashka-Z-Leto [24]

Answer: The handle of a frying pan on the stove

Explanation: Convection is the heat transfer done by the movement of a fluid, or the molecules on it. This can happen by the change on density from fluids, when a fluid tempeture rise, it expands, rising his volumen and decreasing his density. When this happens the fluid becomes lighter, so it moves.

The handle of a frying pan gets hotter but no molecular movement is done. It is between the same material there is a energy transfer from the source to the rest of the pan. This is called Conduction.
