WAEC Physics Obj And Essay/Theory Solution Questions and Answer – MAY/JUNE 2018 Expo Runz.
SECTION B – ANSWER 3
Diffraction is the ability of waves to bend around obstacles in their path
Critical angle is the highest angle of incidence in a denser medium when angle of refraction in the less dense mediumis 90 degrees
The refractive index of the glass is obtained as follows
The refractive index(n)=sini/sinr=sin46/sin90=0.7193/1
f1=3v/4l =>closed pipe
but 3fo=f1=>closed pipe
Also f1=2fo=>open pipe
i)Nature of surface
ii)medium of transmission
i)state or phase of the substance (i:e solid,or gas)
ii)temperature of the meduim
ii)specific heat capacity of the body
the statement means that the amount of heat energy required to change 1kg of liquid mercury to gaseous mecury without change in temperature is 2.72*10^5jkg^-1
V^2/R t = MLv

12a) This is defined as the amount of energy that must be supplied to a nucleus to completely separate it’s nuclear particles (nucleons)
i) They have short wavelength and high frequency.
ii) They are highly penetrating.
iii) They travel in straight lines.
iv) They don’t require material medium for their propagation.
i)It is used in production of electricity.
ii)It is used to study and detect charges in genetic engineering.
iii)It is used in agriculture.
iv)It is used in treatment of cancer.
E = hf-hfo
but f = v/landa
E= v/landa.h – wo
Where wo = hfo = work function
landa = wavelength
hf = hfo – E
f = hfo – E/h
f = wo – E/h
Recall; that v = f landa
Therefore f = v/landa = 3×10^8/4.5×10-7
=3/4.5 × 10^8+7
f = 6.6×10^14Hz
E = hf
=6.6×10^-34 × 6.6×10^14Hz
Energy of the photoelectron E = hf – vo
=Energy of incident electron – work function
=4.356×10^-19J – 3.0×10^-19J
SECTION A – ANSWER 5
Strain can be defined as the ratio of extension per unit length
Let original length=L
i) Silicon Dioxide
ii) Silica Powder
iii) Germanium Tetrachloride
i) Ferromagnetic material
ii) Diamgentic material
iii) Pamangentic material
An intrinsic semiconductor is an undoped semiconductor that is a pure semiconductor without any significant dopant species present.
The P Type semiconductor is a type of semiconductor that carries a positive charge, while the N type semiconductor carries a negative charge .
Range = u²Sin2tita/g
At maximum range
Sin2tita = 1
2tita = 90dgrees
Tita = 90/2 = 45degree
Maximum height reached = u²sin²tita/2g
Given constant = 2.9×10^-3mk
Temperature = 57degreeC = (57+273)k = 330k
Using landamaxT = constant
landamaxT330 = 2.9×10^-3
landamax = 2.9×10^-3/330
landamax = 8.788×10^-6m
The speed of electromagnetic wave, v = 3×10^8m/s
Using V = f landa
f = v/landa
LASER stands for Light Amplification by Stimulated Emission of Radiation.
A laser is a device that emits a beam of coherent light
