Answer:

<em>Rigid plates that move around Earth's surface is called tectonic plates. </em>

Explanation:

Lithosphere is rigid and relatively cold and is the outer surface of the planet. The convective motions of maintenance break the lithosphere into plates.

This place that a form can move in any direction, can move towards each other, can move away and push each other which is the reason for formation of mountains for shifting of continents for making of ocean basin.

A certain photon has a frequency of 634x1012 Hz. What is the photon's wavelength in a vacuum? Enter your answer in nm (x10-9 m).
Shtirlitz [24]
<h3>Answer:</h3>

4.73 × 10^4 m

<h3>Explanation:</h3>

From the question;

Frequency of the photon = 634 × 10^12 Hz

We are required to calculate the wavelength of the photon.

We need to know the relationship between wavelength and frequency of a wave.

The relationship between f and λ is given by;

c = fλ

Where c, is the speed of light, 2.998 × 10^8 m/s

Therefore, to get the wavelength we rearrange the formula such that;

λ = c ÷ f

  = 2.998 × 10^8 m/s ÷ 634 × 10^12 Hz

  = 4.73 × 10^-5 m

But we require wavelength in nm

1 M = 10^9 nm

Therefore;

Wavelength = 4.73 × 10^-5 m × 10^9 nm/m

                    = 4.73 × 10^4 m

Hence, the photon's wavelength is 4.73 × 10^4 m
