Description
"Refraction of Light" Light Phenomenon PPT Courseware 5
Small experiment:
Insert a pen into a glass of water at an angle. What do you observe?
Activity 1 Observe what happens when light passes from air to water
Guess whether the position of the light spot changes after pouring water?
Communication After pouring water, the position of the light spot changed
Conclusion The propagation direction of light when it is incident from air into water __
refraction of light
When light is incident obliquely from one medium into another medium, the phenomenon of propagation direction ________ is called refraction of light
Several terms related to refraction of light
Laws of refraction of light
1. The refracted ray is on the same plane as the incident ray and the normal; and the refracted ray and the incident ray are always separated on both sides of the normal.
2. When the angle of incidence increases, the angle of refraction also increases.
3. When light slants from air into water (or other transparent media), the refracted ray deviates from the normal, that is, the refraction angle is smaller than the incident angle; when light radiates from water (or other transparent media) to air, the refracted ray deviates from the normal, That is, the angle of refraction is greater than the angle of incidence
4. When vertically irradiated, the propagation direction remains unchanged.
Conclusion: When you look at an object in the water from the shore, the object becomes shallower; when you look at an object on the shore from the water, the object becomes taller. You see an elevated virtual image.
practise:
1. When you pour water into a basin, you will see that the depth of the basin bottom changes ( ). When a diver observes the trees on the shore from underwater, the depth of the tree will change ( ).
2. In the calm lake water, you can see the scene of "fish swimming in the clouds". The fish and clouds you see are actually ( )
A. Clouds are virtual images, and fish are real objects. B. Clouds are virtual images, and fish are real objects.
C. Clouds and fish are both real images. D. Clouds and fish are both virtual images.
Discussion and reflection
As shown in the figure, there is a beam of light slanting towards point A at the bottom of the cup. When water is added, the illuminated point at the bottom of the cup will be at ( )
A is still at point A,
B is to the left of point A,
C is to the right of point A
Reinforcement and feedback:
1. When a beam of light slants from glass into the air, try to determine the medium, incident light, normal, reflected light and refracted light based on the law of reflection and refraction of light.
