Parallel light waves hit the surface of a still lake and reflect in the same direction and the interaction of light and matter that it illustrates is called regular reflection. Regular reflection occurs whenever the reflecting surface is very smooth. The surface of the still lake is smooth. I hope the answer helps you.
Answer:
The Light We See
Visible light includes all the wavelengths of light that the human eye can detect. It allows us to see objects in the world around us. Without visible light, we would only be able to sense most objects by sound, touch, or smell. Like humans, most other organisms also depend on visible light, either directly or indirectly. Many animals—including predators of jellyfish—use visible light to see. Plants and certain other organisms use visible light to make food in the process of photosynthesis. Without this food, most other organisms would not be able to survive.
Q: Do you think that some animals might be able to see light that isn’t visible to humans?
A: Some animals can see light in the infrared or ultraviolet range of wavelengths. For example, mosquitoes can see infrared light, which is emitted by warm objects. By seeing infrared light, mosquitoes can tell where the warmest, blood-rich areas of the body are located.
Incandescence
Most of the visible light on Earth comes from the sun. The sun and other stars produce light because they are so hot. They glow with light due to their extremely high temperatures. This way of producing light is called incandescence. Incandescent light bulbs also produce light in this way. When electric current passes through a wire filament inside an incandescent bulb, the wire gets so hot that it glows
Answer:
Acceleration will be 
Explanation:
We have given that car is traveling with speed 34 miles per hour
So initial speed of the car u = 34 miles per hour
After 2 hour speed will be 84 miles per hour
So final speed V = 84 miles per hour
Time = 2 hour
From first equation of motion we know that 
So acceleration 
Answer:
figure (a) L1 is series and L2 is parallel to L3
figure (b) L2 and L3 are parallel to L1
