Which electromagnetic radiation:
a)will diffract round hills
b) can be used to cook food
c)can themometers detect
d)cause skin cancer
e)is ued when taking a photograph with an ordinary camera
thanks!!
I will be happy to critique your thoughts. Some have multiple answers, although the teacher may not realize that. Choose from among the following:
infrared, visible, radio (VLF), microwave, ultraviolet, xray and gamma ray
I just found some of the answers out- which I didn't know before, and I have found I don't know some of the other ones, could you tell me if the answers are wrong or right? and if you could help me with the answers I don't know, that would be great-
will diffract around hills - ??
give people a sun-tan- ultraviolet
can be used to food- Infrared
Can themometers detect- Infrared
Can cause skin cancer- Ultra violet
Used when taking a photograph with an ordinary camera- ??
Causes Ionisation- ??
thanks!!
Great job on your answers so far! Here's the breakdown of the correct answers:
a) Electromagnetic radiation that will diffract around hills is radio waves. Radio waves have long wavelengths that allow them to diffract and bounce around obstacles like hills.
b) The electromagnetic radiation that can be used to cook food is microwave radiation. Microwaves have the right wavelength and energy to generate heat and cook food efficiently.
c) Thermometers can detect infrared radiation. Infrared radiation has longer wavelengths than visible light and is typically emitted by objects that have heat.
d) You are correct, ultraviolet radiation can cause skin cancer. Prolonged or excessive exposure to UV radiation, such as from the sun or tanning beds, can increase the risk of skin cancer.
e) The electromagnetic radiation used when taking a photograph with an ordinary camera is visible light. Visible light falls in the range of wavelengths that the human eye can perceive and is used to capture images in photography.
For the last two questions:
- The electromagnetic radiation that causes ionization is gamma ray radiation. Gamma rays have very short wavelengths and high energy levels, which makes them capable of ionizing atoms and molecules.
- The electromagnetic radiation that causes sunburn or a tan is also ultraviolet radiation. UV radiation can cause the skin to produce more melanin, which leads to a tan, but it can also damage the skin cells and cause sunburn.
I hope this helps! Let me know if you have any further questions.
