They use their eyes
yes, well atleast I think so!
Their ears, of course.
No, not all electromagnetic waves are invisible. While some, such as radio waves, microwaves, and infrared waves, are invisible to the human eye, others, like visible light, ultraviolet light, and X-rays, can be seen or detected with the right equipment. For example, visible light waves are responsible for the sense of sight.
Llamas have well-developed senses that help them navigate their environment. They possess excellent eyesight, allowing them to see a wide range of colors and detect movement from afar. Their sense of hearing is also acute, enabling them to pick up sounds that humans might miss. Additionally, llamas have a good sense of smell, which they use to identify threats and communicate with other llamas.
The intensity of light waves is a measure of the energy carried by the waves. It is proportional to the square of the amplitude of the waves. The intensity of light waves determines how bright the light appears to us.
Some insects use ultraviolet waves to find nectar. The ultraviolet light leaves marks on flowers, and the insects can sense them and find the nearby nectar.
No, electromagnetic waves such as radio waves, microwaves, and visible light are not able to be detected by the sense of smell because they do not have a scent. These waves are typically detected by instruments or devices designed to pick up their specific frequencies.
Ultraviolet waves are smaller than light waves.
No because light waves are stronger and brighter and sound waves are light and dull
Light waves do not emit radiation, light waves are radiation.
Optical light waves are "Electromagnetic" waves. The colour seen is dependent on the wavelength of the light. Electromagnetic waves are transverse waves where the oscillation is 90 degrees to the direction of travel (unlike sound waves which are longitudinal).
The eyes sense light and images, the nose senses odors, the ears sense sound waves, the skin senses touch, temperature, and pain, and the tongue senses taste.
