Cards in this deck (7)
- 1What are the 7 Electro magnetic Spectrums?Radio Waves
Micro waves
Infrared waves
Visible Light
UV (Ultra Violet)
X ray
Gamma ray - 2What is diffraction?The way the wave is spread out as a result of passing through a narrow gap.
- 3Why does some diffract more than the others?This is because when there is a larger gap the waves don't bend as much. While when there is a smaller gap, to be able to fit they bend. But if the gap is to small the waves will reflect.
- 4What is refraction?Refraction is the changing directions of a wave due to changes in speed.
- 5What is happening here?The ray entes at an angle. Then it slows down as it goes inside and bends towards the normal line. As the ray leaves the block, the ray bends away from the normal line and continues going straight.
- 6What is apparent Depth ?Apparant Depth is when the refraction of light of the surface of water makes swimming pool looks shallower than it really is
- 7What are the good and Bad thing of radio waves?Good - Captures and emits waves from radio stations. Giving communication, music, news
Bad - Some people say you can get brain tumors and cancer.
