In a two-slit experiment using coherent light, the distance between the slits and the screen is 1.10 m, and the distance between
Paul [167]

Answer:

D) 763 nm

Explanation:

Calculation for the wavelength of light

Using this formula

Wavelength of light=Delta Y*Distance / Length

Where,

Delta Y represent the 2nd order bright fringe

Length represent the distance between both the slits and the screen

Distance represent the Distance between the slits

Let note that cm to m = (4.2) x 10^-2 and mm to m= ( 0.0400x 10^-3)

Now Let plug in the formula

Wavelength of light=[(4.2 x 10^-2m)(0.0400 x 10^-3m) / 2(1.1m)]*10^-7 meters

Wavelength of light=[(0.042m) (0.0004m)/2.2m]*10^-7 meters

Wavelength of light =(0.0000168m/2.2m)*10^-7 meters

Wavelength of light =7.63 *10^-7 meters

Wavelength of light =763 nm

Therefore the Wavelength of light will be 763 nm

An iron rod and a copper rod of equal length are each held by hand at one end, with the other end in the flame from a Bunsen bur
lara31 [8.8K]

Answer:

Iron has a higher heat capacity than copper

Explanation:

The heat capacity of a substance is defined as the amount of heat required to raise the temperature of an object by 1°C.

The higher the heat capacity of a substance, the longer the time it takes for the substance to become hot when heated.

Since the copper rod becomes too hot to hold much sooner than the iron rod, it means that iron has a higher heat capacity than copper.

Dominoes standing in a row will fall if the first one is tipped towards the others. How does the law of convection of energy des
Amanda [17]
When placing each domino upright, potential energy is conserved in that domino. When kinetic energy is initially added into the first domino, this energy converts the next domino's potential energy to kinetic energy, which is transferred to the next domino afterwards.

What is gravity? Is gravity a force?
vodka [1.7K]

Answer:

Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull.

Explanation:

The more massive an object is, the stronger its gravitational pull is. Earth's gravity is what keeps you on the ground and what causes objects to fall.
