the weatherman reports the storm waves are about 2 meters high and 35 meters apart. What properties of waves is the reporter des
8_murik_8 [283]

Answer:

Amplitude and wavelength

Explanation:

- The amplitude of a wave is the maximum displacement of the wave, measured with respect to the equilibrium position (so, for a water wave it is the maximum height of the wave relative to the equilibrium position)

- The wavelength of a wave is the distance between two consecutive crests (or throughs) of a wave. So, for a water wave, it is the distance between two consecutive waves

Therefore, in the example in the problem we have:

- 2 meters corresponds to the amplitude

- 35 meters corresponds to the wavelength

What is the frequency of radiation whose wavelength is 0.80 nm ? express the frequency in inverse seconds to three significant d
Mashcka [7]
The relationship between the frequency (f) of an electromagnetic wave, the speed of the wave (which is the speed of light, c) and its wavelength \lambda is given by
f= \frac{c}{\lambda}

Since the wavelength of the radiation in the problem is \lambda= 0.80 nm = 0.80 \cdot 10^{-9} m, by substituting numbers in the formula we  can get the frequency:
f= \frac{3 \cdot 10^8 m/s}{0.80 \cdot 10^{-9} m} =3.75 \cdot 10^{17} s^{-1}
