Answer:

λ = 2.8 m

Explanation:

Given data:

Frequency of radio wave = 106.7 ×10⁶ Hz

Wavelength of radio wave = ?

Solution:

Formula:

Speed of wave = frequency  × wavelength

speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s = 106.7 ×10⁶ Hz × λ

Hz = s⁻¹

λ = 3×10⁸ m/s / 106.7 ×10⁶ Hz

λ =  3×10⁸ m/s / 106.7 ×10⁶ s⁻¹

λ =  0.028×10² m

λ = 2.8 m

During the first half of the 20th century, the theory of plate tectonics was developed. Evidence supporting this theory included
Makovka662 [10]

A) GPS monitoring and satellite imagery of crustal movements

Explanation:

The most recent evidence supporting the theory of plate tectonics is the use of  GPS monitoring and satellite imagery of crustal movements.

GPS denotes Global Positioning Systems.

Satellite imagery is a recent advancement in the study of moving plates.

  • The global positioning system uses the position of a system of satellites in space to delineate positions on earth.
  • It works on the principles of triangulation and this helps to fix positions of objects on the earth surface.
  • With this, the change in position of the plates can be recorded by known fixed positions of objects.
  • Satellite imagery helps to map changes in terrain with time.
  • Images can be correlated through time and the shift in terrains delineated.
