NASA team discovers sound travels with two speeds on Mars

NASA scientists working on the Perseverance rover have discovered that sounds on Mars travel at two speeds depending on their frequency. They found this by comparing sounds from a higher pitched laser targeting a rock with the low pitched hum of the Ingenuity helicopter. ThePrint’s Sandhya Ramesh explains the science behind the new findings.

This segment is such a rare gem. Especially in India hardly anyone is talking about these discoveries. Kudos to you

[naveenagrawal]

Really impressed by your videos! You target the broader audience pretty well!

[sujathachandrasekaran]

Love her program. Exciting. She covers varying fields of science which is not easily accessible to most of us but would love to know!

Good idea to utilise difference in speeds of waves for improving communication. Even for EM waves such differences in speeds can arise.

FYI - Speed of sound is not constant on Earth....it depends on couple of factors and it varies accordingly....

the helicopter is it real or only a model running in a 3d universe?

Looks like this video was made in haste.

Please increase the volumes mohana. This is happening consistently. I almost went deaf today at the end of the video because my earphones has 100% volume 😂
So increase your voice volume output if u don't want us deaf XD 😆
