Scientific Facts.

What I need to improve:

1. The speed formula: Speed= Distance / time

2.Distance traveled = Area under graph
                                  Area of triangle A + Triangle B + Triangle C

3.Remember formula     a= v-u/t

4. A resistor and a power supply are two things which affect the current size.

5.


6. Potential difference is Initial Voltage - Current voltage.

7.


8. The number of waves per second is the FREQUENCY
    The time Taken for each was is it's PERIOD

9.Law of reflection is          angle of incidence = angle of reflection

10. Diffraction:

Reflection, refraction and diffraction

3.14 Recall that light waves are transverse waves which can be reflected, refracted and diffracted
