Observation:
When the straw is kept perpendicular we see that no change is observed.
Once the straw is kept slanting the straw appears to be bent.]]> 2016-10-17 04:56:27 UTC https://padlet.com/suja_d_ois/refract/wish/131036248 https://padlet.com/suja_d_ois/refract/wish/131036276 Activity 2; 
Observation : 3. The coin shifted its position (heard sound of the coin) 
4. The coin looks larger than it was when the water was not poured. This is because there is a disturbance in the medium of light.

2. The straw appears larger than the original size 
3. The water made the straw change direction. ]]> 2016-10-17 04:57:25 UTC https://padlet.com/suja_d_ois/refract/wish/131036300 https://padlet.com/suja_d_ois/refract/wish/131036331 Activity 4
Observation :
The line joining the object and the image is not perpendicular. The light bends towards the normal when the medium changes from the air to the glass slab]]> 2016-10-17 04:57:56 UTC https://padlet.com/suja_d_ois/refract/wish/131036331 sumi2606 https://padlet.com/suja_d_ois/refract/wish/131036335 Observation : The image observed was at a different angle than the actual position of the line. The needles were seen at a different angle. The position changed after observation.]]> 2016-10-17 04:58:04 UTC https://padlet.com/suja_d_ois/refract/wish/131036335 https://padlet.com/suja_d_ois/refract/wish/131036398 OBSERVATION:- activity 1
The straw appears to be larger in water and slightly bent when its perpendicular it appears to be in the same shape.]]> 2016-10-17 04:58:52 UTC https://padlet.com/suja_d_ois/refract/wish/131036398 https://padlet.com/suja_d_ois/refract/wish/131036464 Observation:when light ray passes through the glass slab it deflets from the normal at a certain angle. As it reflects back it again at a different angle]]> 2016-10-17 04:59:51 UTC https://padlet.com/suja_d_ois/refract/wish/131036464 https://padlet.com/suja_d_ois/refract/wish/131084423 2016-10-17 11:04:13 UTC https://padlet.com/suja_d_ois/refract/wish/131084423
