What are the maximum magnifications of the lm, tem, and sem?

LM, TEM, SEM are microscopes used to study small objects particularly Cells.

Light Microscope or LM, also known as Optical microscope, has the maximum magnification of x1500, this means that in using light microscope the size of the object is magnified 1500 times.

Transmission Electron Microscope or TEM has a maximum magnification of x500000 and produces a 2D image of the sample.

Scanning Electron Microscope or SEM has a maximum magnification of x100000 and produces a 3D image of the sample.

a) 1.092 m/s

b) 0.33 m

c) 0.25 m

Explanation:

To start with, from the formula of wave, we know that

v = f λ, where

v = velocity of wave

f = frequency of the wave

λ = wavelength of the wave

Again, on another hand, we know that

T = 1/f, where T = period of the wave

From the question, we are given that

t = 2.7 s

d = 0.66 m

λ = 5.9 m

Period, T = 2 * t

Period, T = 2 * 2.7

Period, T = 5.4 s

If T = 1/f, then f = 1/T, thus

Frequency, f = 1/5.4

Frequency, f = 0.185 hz

Remember, v = f λ

v = 0.185 * 5.9

v = 1.092 m/s

Amplitude, A = d/2

Amplitude, A = 0.66/2

Amplitude, A = 0.33 m

If the other distance travelled by the boat is 0.5, then Amplitude is

A = 0.5/2

A = 0.25 m
