First day science reflection and refraction of light -- the first day of science reflection and refraction of light exercises First, fill in the blank: 1, in the lake, you can see the trees on the shore in the water reflection, this is the light of the water, look at the bottom of the tank rises, the water becomes shallow, it is light in 2, when the incident ray is normal to close when the angle of reflection angle will O Full name Phenomenon, swimming pool charge Phenomenon. When reflected light is perpendicular to incident light.. When the incident light is 20 degrees angle to the plane mirror, the reflection angle is The angle between the reflected light and the incident light is increased by 3, and a beam of light is projected onto the plane mirror. When the incident angle is increased by 10, the 4 plane mirror imaging is caused by the imaging of the light, the image and the size of the object. It is characterized by the distance from the mirror to the mirror and the mirror of the object, 5, the object placed in front of the plane mirror 2 m, it is like the distance to the mirror, for this time, the object, the distance between the image as. If the object is further away from the plane mirror 1 m, 6, standing on the clear stream side, see the fish position in the stream, than the actual fish, see the stream side of the person than the actual 7, the eye refraction system is. Hyperopia can be worn (filled with high or short) (fill in deep or shallow), while in water Consisting of, in which the main role of the lens made of the eye to correct.. Kilometers, then the light from the sun travels to the earth Eight 8. When light is reflected or refracted, the path of light is 9, and light travels in vacuum at a speed of 2
