A microwave absorbing device can be created to absorb the microwaves in the air from the communication signal plant or lines.

Cell phones or towers of cell communication, or towers can emit a frequency of 900 to 1800 MHz microwaves which are responsible for negatively affecting the health of birds.This have been proved that it can cause thinning of the skulls of the chicks and thinning of their egg shells which can reduce the population of local bird species. Thus the development of microwave absorbing device can help in reducing the negative influence of microwaves on bird species population.

Statement which is true about rock cycle is  that sedimentary rock can revert to metamorphic rock but never to igneous rock.

What are sedimentary rocks?

They are the types of rocks which are formed as a result of accumulation of minerals or organic particles at the surface of the earth.Sedimentation is the name given to a collective process which cause the particles to settle.

The study of sedimentary rocks is useful in civil engineering and as important sources of coal, fossil fuels and ores.The color of sedimentary rock is often determined by iron content and sometimes due to the presence of organic matter.

They are classified based on origin in to 4 types which are clastic, biochemical ,chemical and other sedimentary rocks.While based on composition they are classified as siliciclastic,carbonate ,evaporite,organic rich,siliceous ,iron-rich and phosphatic sedimentary rocks.

b. The distance from the still water level to the crest needs to be changed to 1 meter.
c. The distances from the still water level to the trough and the crest need to be changed to 1 meter.
d. The distance between the two crests needs to be changed to 2 meters.

Answers

Answer:

C. The distances from the still water level to the trough and the crest need to be changed to 1 meter.

Explanation:

I took the test also I want to thank the people in the comments for giving me the correct answer

In the image, the distances from the still water level to the trough and the crest needs to be changed to 1 meter. Thus, the correct option is C.

What is wavelength?

Wavelength is the spatial period of a periodic wave. It is the distance over which the wave's shape repeats periodically. The wavelength is the distance between two crests and troughs. Wavelength is the distance which is measured by the unit meter. Wave height is the vertical distance between the crest and the trough of a wave.

For example: Still-Water Line is the level of the lake surface if it is perfectly calm and flat. The crest is the highest point on the wave above the still-water line.

The distances from the still water level to the trough and the crest need to be changed to 1 meter in the diagram to correct the wave height and wavelength of the wave.

Therefore, the correct option is C.
