When a ray passes from air into glass the direction in which the light ray is travelling changes. The light ray appears to bend as it as it passes through the surface of the glass. When a light ray passes from air into water a similar thing occurs: the light ray is bent as it strikes the surface of the water.
The part of the electromagnetic spectrum closest to radio waves is <u> microwaves</u>.
The wavelength of radio waves ranges from 10 cm to more than 1 km. The part of the electromagnetic spectrum that occurs closest to the radio waves is called the microwave region.
Microwaves have wavelengths ranging from around 1 mm to 10 cm.
The waves overlap in the region of 10 cm.
Thus, the region of electromagnetic spectrum closest to radiowaves is <u> microwaves.</u>
Answer: 9.0 atm
Explanation:
To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
Thus new pressure of 150 ml of a gas that is compressed to 50 ml is 9.0 atm
