No. Bluetooth is designed for very low power use, and the transmission range is
typically only around 10m (about 30ft). High-powered Bluetooth devices will enable
ranges up to 100m (300ft). Considering the design philosophy behind Bluetooth,
even the 10m range is adequate for the purposes Bluetooth is intended for.
Cellphones must be able to communicate reliably with the nearest cellular tower.
Transmit power output can range up to as much as a few watts.
Yes, electromagnetic radiation includes infrared radiation, which has longer wavelengths than visible light. Infrared radiation is not visible to the human eye but can be felt as heat. It is part of the electromagnetic spectrum, which encompasses all forms of electromagnetic radiation.
No. Cell phone radiation is radio waves in the Megahertz and Gigahertz frequencies. This does not break up molecules in your body. Cell phone radiation is harmless. Solar radiation is infra red, visible light and ultraviolet light which can burn you and break up molecules on your skin, and also particle radiation which can break up molecules deep in your body.
No, they are not. X-rays have a higher energy than UV radiation, and they have the potential to do more damage to tissue.
Gamma radiation
Photons of UV B radiation are more energetic than photons of UV A radiation. UV B radiation has a shorter wavelength and higher energy compared to UV A radiation, making it more damaging to the skin and eyes.
Every cellphone has limited inbuilt space, if you want to increase your cellphone space than you insert a memory card in your cellphone.
No.
China has the world's biggest cellphone network in terms of customers which are more than 525 million (January 2010).
more than that
Yes, electromagnetic radiation includes infrared radiation, which has longer wavelengths than visible light. Infrared radiation is not visible to the human eye but can be felt as heat. It is part of the electromagnetic spectrum, which encompasses all forms of electromagnetic radiation.
No more than it damages your cellphone or smartphone.
No. Cell phone radiation is radio waves in the Megahertz and Gigahertz frequencies. This does not break up molecules in your body. Cell phone radiation is harmless. Solar radiation is infra red, visible light and ultraviolet light which can burn you and break up molecules on your skin, and also particle radiation which can break up molecules deep in your body.
Ultra violet radiation has more energy (E=hf) than visible radiation.
No. No creature is impervious to radiation. However, some insects are more tolerant of radiation than humans are.
No, they are not. X-rays have a higher energy than UV radiation, and they have the potential to do more damage to tissue.
yes, x ray radiation photons have more energy than infrared waves
more than 5 billion people use mobile phones worlwide so that is more than 70%
