200 Incident Reflected Absorbed Transmitted Look closely at the picture above. How light travels? What happens when light travels from one medium to another? Since visible light is an electromagnetic wave it does not require a medium to propagate. However, its speed changes as it moves from one medium to another with different densities. If it occurs, light bends Direction: Identify how light behaves as described in each item. Choose your answer inside the box

1. It is the bouncing of light as it hits a material.

2. It is the passing of light through some materials.

3. It is the separation of white light into its component colors.

4. It is the material's taking in of light and not reflecting it back.

5. It is the bending of light as it passes through a different material.

4. A park shaped like a rectangle has a length of 38 meters and a width of 26 meters. If trees are planted on its sides with gaps of 2 meters in between. How many trees are needed?

64 trees is the answer of your question.

------------------−−−−−−−−−−−−−−−−−−

\huge\color{iron}\bold{Solution:}Solution:

38 \times 2 + 26 \times 238×2+26×2

= 76 \times 52=76×52

= 128=128

The number of trees is 128, then devide by 2. So,...

= 128 \div 2=128÷2

= 64=64

So, 64 trees are needed.
