2. Why are some energy waves harmful to humans? Give an example of an energy wave which could harm us.
3. How does the medium the wave is traveling through affect its speed? In which medium (solid, liquid or gas) does waves travel the fastest? Why?
1. What happens to the frequency of a wave if I change its wavelength? How does changing the wavelength affect the energy of the wave?

Changing the wavelength will result in a different type of frequency because the wave is changed. When the wavelength is changed then the frequency will go higher or lower because of the way you change it.

If you change the wave length you will get a higher or lower frequency. By changing the wavelength you make the energy go either faster or slower and change the energy.

1. If the wavelength is short then the frequency is high, but if the wavelength was long the frequency would be low. If the wavelength is long the frequency is long and low so there is less energy making it move, but if the wavelength is changed to short the frequency is high and fast which uses more energy to make it move.

If the wave length is shorter then the faster the frecuency is,if the wavelength is longer then the frequency will be slower. changing the wavelenght effects th energy of the wave because a wave with a short wave length carries more energy than a wave with a long wave length.

The frequency wills decrease because the longer and bigger it is it takes more energy . The way its uses more energy is because it is bigger.

1. According to wiki answers when the wavelength changes the time increases or decreases. Changing the wavelength affects the shorter the wavelength means there is more energy. If there is a long wavelength there is less energy.

BlogsBlogs will be complex questions addressing specific topics covered in class. Blog groups will be assigned each quarter and class time will be given for your responses. New blogs will be posted on Monday and evaluated on Friday. There will NOT be a blog every week. A scoring guide will be available will be used to evaluate the posts. Evaluations will be conducted by the teacher and fellow students. Archives
