Given that the frequency of a wave is 9.12x10^-12 Hz, what must be the
polet [3.4K]

Answer:

The wavelength of wave is 0.33 ×10²⁰ m.

Explanation:

Given data:

Frequency of wave = 9.12×10⁻¹² Hz

Wavelength of wave = ?

Solution:

Formula:

Speed of light = wavelength × frequency

c = λ × f

λ = c/f

This formula shows that both are inversely related to each other.

The speed of light is 3×10⁸ m/s

Frequency is taken in Hz.

It is the number of oscillations, wave of light make in one second.

Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.

Now we will put the values in formula.

λ = 3×10⁸ m/s  / 9.12×10⁻¹² Hz

Hz = s⁻¹

λ = 0.33 ×10²⁰ m  

The wavelength of radiation is 0.33 ×10²⁰ m  .

What does the principle of faunal succession state?
irina1246 [14]

<u>Answer:</u>

The principle of faunal succession state <em>"Specific groups of organisms have followed one another in a definite sequence through the Earth's history."</em>

<u>Explanation:</u>

Faunal succession basically means is that the fossils of the flora and fauna of different eras can be found in a specific order and never in the same strata. This allows the geologists to determine the time sequence and also to identify the various strata by dating the fossils that are found in each of them. The older version of fossils are found beneath the fossils of modified versions. For example fossils of simple feathers that cannot support flight are found to be succeeded by fossils of more complex feathers.
