a soap film is viewed in white light. if the film is much thinner than the wavelength of blue light, what is the appearance of the film?

Answers

Answer 1

Answer: When a soap film is viewed in white light and the film is much thinner than the wavelength of the blue light, the film will seem to be totally transparent. The thin film will reflect no visible light. It actually depends on the thickness of the film through which the light is being transmitted. I hope the answer helps you.

What is the mass of an object weighing 63 N on Earth?

Answers

Weight expressed in Newtons is expressed in the equation whereby Weight= the mass of an object * the force of gravity. The force of gravity on earth is a constant 9.8 meters per second squared. Therefore if weight (w) = 63 N and the force of gravity is 63 N then the mass must equal 6.43 kg. Because the equation for weight is w=mg so 63 N (w) = m * 9.8 m/s^2.

How does crater density relate to the moon’s geologic history?

Answers

The crater density related to the moon's geologic history through its crater on the surface. The greater density it has, the older the surface must be. This means that the crater can actually determine how old its geologic history must be.

Answer:

High crater density is associated with older surfaces.

Radio waves travel at the speed of light, which is 3.00 u 108 m/s. How many kilometers will radio messages travel in exactly one year?

Answers

Answer:

Distance traveled will be $9.462* 10^(12)km$

Explanation:

We have given speed of the light $v=3* 10^8m/sec$

We have to find the distance traveled by light in 1 year

We know that 1 year = 8760 hour

And 1 hour = 60×60 = 3600 sec

So 1 year $=8760* 3600=3.154* 10^(7)sec$

We know that distance = speed × time

So distance traveled by light in one year $=3.154* 10^7* 3* 10^8=9.462* 10^(15)m$

We have to fond the distance in km

As we know that 1 km = 1000 m

So $9.462* 10^(15)m=(9.462* 10^(15))/(1000)=9.462* 10^(12)km$

Final answer:

Radio messages will travel approximately 9.46 x 10^12 kilometers in exactly one year.

Explanation:

Radio waves travel at the speed of light which is approximately 3.00 x 108 m/s.

To find out how many kilometers radio messages will travel in exactly one year, we need to first convert the speed of light into kilometers per second.

Since there are 1000 meters in a kilometer, we divide the speed of light by 1000 to convert from meters to kilometers. Then, we multiply this value by the number of seconds in a year (365 days x 24 hours x 60 minutes x 60 seconds) to get the total distance traveled in kilometers.

In summary, radio messages will travel approximately 9.46 x 1012 kilometers in exactly one year.

How many nitrogen atoms are in one molecule of (NH4)2SO4?

Answers

15 nitrogen atoms are in one molecule

Final answer:

In one molecule of (NH4)2SO4 or ammonium sulfate, there are two nitrogen atoms.

Explanation:

The molecule (NH4)2SO4 is known as ammonium sulfate. This molecule is composed of two ammonium ions (NH4) and one sulfate ion (SO4). The ammonium ion consists of one nitrogen atom (N) and four hydrogen atoms (H). Because the formula indicates there are two ammonium ions (as shown by the subscript '2'), this means the overall molecule of ammonium sulfate contains two nitrogen atoms.
