Choose the correct description of what do we mean when we say that light is an electromagnetic wave and the relationship among w
1 answer:
An electromagnetic wave is the oscillation of electric and magnetic fields that propagate in the space. Electromagnetic waves carry energy and they do not need a medium to propagate (they can travel in vacuum as well).
The correct relationship between the speed of the wave (speed of light, c), the frequency f and the wavelength
is

Answer:
The width of the slit is 0.167 mm
Explanation:
Wavelength of light,
Distance from screen to slit, D = 88.5 cm = 0.885 m
The distance on the screen between the fifth order minimum and the central maximum is 1.61 cm, y = 1.61 cm = 0.0161 m
We need to find the width of the slit. The formula for the distance on the screen between the fifth order minimum and the central maximum is :
where
a = width of the slit
a = 0.000167 m
a = 0.167 mm
So, the width of the slit is 0.167 mm. Hence, this is the required solution.
