Icy is slippery because when your hands make contact with the ice cube the heat from your hand already starts to melt the ice, and when it ice melts it becomes water and water isn't the easiest thing in the world to have a grasp on...

Because ice is less dense than liquid water,
its melting point is lowered under high pressures.

A long standing theory says that this is what causes ice to be slippery:

As you step on it, the pressure of your weight causes the top layer to my into water.

A two slit pattern is viewed on a screen 1.00m from the slits if the two third-order minima are 22.0 cm apart what is the width
Bingel [31]

Answer:

4.4 cm

Explanation:

Given:

Distance of the screen from the slit, D = 1 m

Distance between two third order interference minimas, x = 22 cm

Let's say, minima occurs at:

x_n = (n + \frac{1}{2}) \frac{wL}{d}

We have:

2x_2 = 2(2 + \frac{1}{2}) * \frac{w*22}{d}

Calculating further for the width of the central bright fringe, we have:

\frac{w}{d} = \frac{22}{5}

= 4.4 cm

Note: w in representswavelength
