Hi Davina :) Yes, partial reflection and refraction will occour because the incident ray will refract if it has not reached the critical angle. Once the ray reaches the critical angle of the first media they ray will start to totally internally refract, in summary. Yes it will unless the angle is past the critical angle
Answer:
a binary phase or binary compound is a chemical compound containing two different elements. Some binary phase compounds are molecular, e.g. carbon tetrachloride. More typically binary phase refers to extended solids.

Explanation:
Given that,
Ey = 375•Cos[kx - (2.20 × 10¹⁴t)]
Speed of light
c = 3×10^8m/s
What is the wavelength?
Generally,
The wavelength of electromagnetic wave is give as
Ey = Emax•Cos(kx—wt)
k = 2π/λ
w = 2πf
Ey = Emax•Cos(2πx/λ—2πft)
Comparing this to the wave equation given,
We notice that,
2πx/λ = kx
Also,
2.20 × 10¹⁴t = 2πft
t cancels out
2.20 × 10¹⁴ = 2πf
f = 2.20 × 10¹⁴ / 2π
f = 3.5 × 10¹³ Hz
Since we are given that
c = 3×10^8m/s
Then, using relationship between c, v and λ.
c = fλ.
λ. = c/f
λ. = 3×10^8 / 3.5 ×10¹³
λ. = 8.57 × 10^-6m
λ. = 8.57 μm
The wavelength of the electromagnetic wave is 8.57 micro meter (8.57 μm)
