2 eggs cook in a frying pan, which is sitting over a gas burner. Is thermal energy being transferred from the metal pan to the e
2 answers:
Answer:
No, the eggs are in direct contact with the metal pan, which is in direct contact with the gas flame, so this is conduction, not radiation
Reasons:
-Thermal energy is being transferred by conduction.
-Radiation transfers thermal energy by electromagnetic waves.
-Radiation does not transfer thermal energy by direct contact.
Radiation heat transfer is a process where heatwaves are emitted that may be absorbed, reflected, or transmitted through a colder "body". Sun heats the earth by electromagnetic waves. The sun does not come in physical contact with the Earth to transfer heat. (In my opinion, the Earth touching the sun would not be on my to-do list.)

False
Explanation:
As we know that, the Balmer series gives the n values as,
.
.
Now the value of wavelength can be calculated as,
.
Here, .
And .
Now,
.
Therefore,
Therefore, the wavelength of Balmer series lies in visible region which is 547 nm.
