The difference between the two is, well for one
Spectrum: The entire range that the "<em>waves" </em>could be such, as visible light, x-ray's and so on.
Waves: These are different because they aren't telling you or showing the entire spectrum just which they length that they are.

Answer:
1.1ohms
Explanation:
According to ohms law E = IR
If potential difference of a battery is 2.2 V when it is connected across a resistance of 5 ohm and if suddenly the voltage Falls to 1.8V then the current in the 5ohms resistor I = V/R = 1.8/5
I = 0.36A (This will be the load current).
Before we can calculate the value of the internal resistance, we need to know the voltage drop across the internal resistance.
Voltage drop = 2.2V - 1.8V = 0.4V
Then we calculate the internal resistance using ohms law.
According to the law, V = Ir
V= voltage drop
I is the load current
r = internal resistance
0.4 = 0.36r
r = 0.4/0.36
r = 1.1 ohms

Answer:
(A) Acceleration will be 
(b) Time taken will be 
(c) Force will be 
Explanation:
We have given that electron starts from rest so initial velocity u = 0 m/sec
Final velocity 
Mass of electron 
Distance traveled by electron 
From third equation of motion we know that 
(a) So 
(b) From first equation of motion we know that v = u+at
So 
(c) From newton's law we know that force
