Please help me out!I will give you high rate
For each of the following stat statement is false ements, circle T if the statement is true and circle F itf the 1, TF When a wave reaches a boundary between two media and some or all of the wave bounces back into the first medium, this is known as reflection. 2. TF Your eye cannot ordinarily tell the difference between an object and its virtual mage 3. TF When light waves move from one medium into a medium in which they travel more slowly, the light wave is bent away from the normal. The separation of light into colors arranged according to their frequency is called 4. T F 5. T F 6. T F 7. T F 8. T F 9. T F diffraction A camera forms a virtual image on film. The layer of tissue at the back of the eye is the iris. In a far-sighted eye, light focuses in front of the retina. The bending of a wave around an obstruction is called refraction. When the crest of one wave overlaps the crest of another wave, the result is destructive interference. 10. TF A laser beam is said to be incoherent because there is no interference of waves within the beam. Answer the following questions by writing on the blank lines the letters) of the word or phrase the question Choose only one answer unless a
Explanation / Answer
1) rfefliction happends with in the medium only so it is true
2) Your eye cannot ordinarily tell the difference between an object and its virtual image because the light that enters your eye is entering in exactly the same manner as it would without the mirror if there really were anobject where you see the image so it is true
3) it is false , when a light travels from rarer medium to densar medium then it is bending towards the normal.
4) it is false, it is dispersion
5) n0, it is false, camera forms a real image
6) false , it is retina
7) false
8) false, difraction
9) false, constructive
10) false, laser beam is coherent source, it forms an interference pattern
