In the simple case, yes. When there are lenses involved the answer is far more complicated.

Is gravity stronger or weaker than electromagnetic forces?

stronger


Does a magnetic field strengthen on weekend as you move away from the eletromagnet?

No, the strength of a magnetic field does not increase as you move away from the electromagnet. The strength of a magnetic field decreases with distance from the source, following the inverse square law. This means that the magnetic field weakens as you move further away from the electromagnet.


How does distance affect intensity?

Distance affects intensity by following the inverse square law, which states that as distance from a source increases, the intensity of the source decreases by the square of the distance. This means that the further you are from a source of intensity, the weaker the intensity will be.


Non polar substance are stronger or weaker?

they are weaker because the ions of substance have low electromagnetic which have covalent character to be low.


Why can it be said that 'magnetism has no limits'?

This is because out of the four fundamental forces (strong, weak, electromagnetic, gravity) magnetism comes under the electromagnetic force. This has an infinite range so for this reason i think it is said to be without limits. Although the range is infinite, the further you are from the force, the weaker it is. It follows something called the inverse square law. so, if you move twice as far from the source, its intensity will be a quarter of what it was before.


Why does sound get weaker as it travels?

Sound gets weaker as it travels because it spreads out in all directions, causing the energy to be distributed over a larger area. This leads to a decrease in the intensity of the sound waves, resulting in lower volume the further you are from the sound source.


What is the main type of electromagnetic that makes up the solar radiation that reaches earth?

Well techinichally it is just a radiation that comes from the sun and the readiation is a electromagnetic field


What changes will result in a weaker electromagnet?

Increasing the resistance in the wire, reducing the number of coils in the electromagnet, and using a weaker power source will all result in a weaker electromagnet.


Why can you jumper further on the moon than the earth?

Because of the weaker on the moon.


Is there any place on the earth without or the least level of radio frequency- electromagnteic waves to live healthier where is this place in Europe?

No, there's no place on earth with no radio frequency (RF) radiation whatsoever. And if there were it would not be in Europe. Anywhere with dense population is likely to have more electromagnetic energy around. But avoiding radio waves won't make you healthier. The energy of an electromagnetic wave is proportional to its frequency, and the photons of RF radiation are billions of times weaker (more harmless) than those of the infrared radiation that any warm object (such as a human being) gives off, and they're trillions of times weaker than ordinary sunlight, not even counting the ultra-violet, which is really the first part of the spectrum that poses a danger to your health.


What is the loss of a signals strength as it travels away from its source?

The loss of a signal's strength as it travels away from its source is known as attenuation. Attenuation can be caused by factors such as distance, obstacles, interference, and the medium through which the signal is traveling. As a signal travels further from its source, it experiences a decrease in power and may become weaker or distorted.


Why is gravity slightly weaker on the continents than over the oceans?

The Continents are further from the center of the earth, leaving the oceans to be closer which means gravity is slightly weaker
