JAMB EXAM MOST ASKED QUESTION 2019/2020
Welcome to another
edition of (Komzi1.blogspot.com)
Jamb series. Hope you are
getting set for your Jamb
examination?
Here are key
points in Jamb Physics to
aid your studies.
I have prepared the Jamb key points based on hot
topics set in Jamb physics. I will be releasing them
in series of 50 hot Physics questions from all the
Jamb Physics topic.
The 1000 points will cover every topic in Jamb
Physics. However, the key points will not be
arranged topic by topic. As time goes on, I will work
on hot key point series on Jamb Biology,
Chemistry, Mathematics, CRS and the Use of
English. It will be wise you follow up series. Now,
lets go straight to business…..
Key Points on Jamb Physics hot topics (1 to 10)
PHYSICS
1) The classification of Wave are:
Mechanical Wave (E.g Water and Sound Wave)
Electromagnetic Wave (E.g Gamma and X-Rays)
Progressive/Travelling Wave (Water And Sound)
Stationary/Standing Wave (Nodes And
Antinodes)
Longitudinal Wave (E.g Sound Waves)
Transverse Wave (E.g Waves in Pipe and
Strings).
2) Stationary Wave occur when two interfering
waves of the same amplitude and frequency travel
in opposite direction.
3) Velocity of Sound In:
Air is 332m/s
Water (Liquid) is 1435m/s
Iron (Solid) is 5000m/s
4) The velocity of Echo is equal to the total distance
traveled by the sound divided by the time taken.
5) The quality of sound depends on the number of
overtones or harmonics. It makes it possible to
distinguish between two instruments playing the
same note.
6) Vibration can either be free, forced or
resonance.
7) Eclipse occurs due to the travel of light in a
straight line.
8) The application of plane mirrors are Periscope,
Kaleidoscope and Sextant.
9) Refraction occurs at constant frequency.
10) Hydrogen spectrum has all colors of white light,
Sodium vapour has yellow line (spectrum) and
Mercury vapour has Blue and Green spectrum.
11) Another word for electrolysis is the chemical
effect of current.
12) Passage of current through liquid doesn’t obey
Ohms law.
13) Magnetic fields are oval in shape.
14) Angle of dip is 90 degree at the magnetic poles
and zero at the equator.
15) The strength of Magnet is greatest at the pole.
16) All electric charges are multiples of the charges
of an electron.
17) Factors affecting capacitance are: Area of plates,
distance between the plates and dielectrics
between the plates.
18) Examples of dielectric materials are Paraffin
wax, Polythene, Ebonite and Glass.
19) Sliding friction are less than limiting friction.
20) EMF is the algebraic sum of potential difference
acting in a circuit.
21) Electromagnetism is the production of current
from Magnet.
22) In a closed circuit, the induced EMF gives rise to
induced current.
23) Eddy current is used in damping moving coil,
speedometers and induction coil.
24) Transformer steps up or steps down voltage at
the same frequency.
25) The Inductor finds application in choke making
industry.
26) Choke is used for varying current.
27) The induced voltage is equal to the rate of
change of magnetic flux.
28) Solar cells convert sunlight energy directly into
electrical energy.
29) Local action is caused by impurity of zinc plate.
30) Eddy current is reduced by lamination.

31) Induction coil is used to step up voltage in DC
circuit.
32) Generator operates based on the principle of
self induction.
33) DC doesn’t oscillate and as such does not have a
frequency.
34) Telephone receiver or earpiece works on the
principle of magnetic effect of current.
35) Plane mirrors do not enlarge or reduce the size
of object. Object size is the same as image size.
36) Factors affecting resistance are:
Length of conductor.
Area of conductor.
Temperature and
Type of material used.
37) Triangular prism with two convex lenses is used
to produce pure spectrum.
38) If light energy is less than the work function, no
electron will be emitted and vice versa.
39) Work function is the energy that can produce
threshold frequency (W=hf).
40) The uncertainty principle only works for atoms
and not irons.
41) The applications of total internal reflection are
Mirage and Fish view under water.
42) Binding energy is the reason for mass defect.
43) Bismuth is diamagnetic.
44) Current is the rate of flow of charge.
45) Kirchoff’s current law states that the algebraic
sum of currents flowing into the circuit is equal to
the algebraic sum of currents leaving the circuit.
46) Kirchoff’s voltage law states that the sum of all
the voltages around circuit loop is equal to zero.
47) Example of refrigerants are Ammonia and Ethyl
Chloride.
48) Kaleidoscope is designed to obtain different
color patterns.
49) To convert a Galvanometer to Ammeter, a low
resistance called shunt is connected in parallel with
the meter.
50) As temperature increases, the speed of sound
increases.
