waves

Question 1

wave speed (m/s2)

Answer 1

velocity = frequency(Hz) x wavelength(m) V=fλ

Question 2

Frequency

Answer 2

1/peroid(s) f=1/T

Question 3

refractive index

Answer 3

sine of angle of incidence/sine of angle of refraction n=sin i/sin r

Question 4

refractive index (without angles)

Answer 4

speed of light in a vacuum(3x10^8m/s) /speed of light in material n=cv

Question 5

refractive index (critical angle)

Answer 5

1/sine of critical angle n=1/sin C
