What's the difference between ш and щ? I've listened to some audios but I can't really figure it out... They sound the same to my ears! Thanks in advance! Спасибо!Thanks everybody for your help! But with sound is better to notice the difference. Once again, thanks for the helping hand!

Correct pronounce of the letter "ы". I've tried many times but I can't seem to pronounce it properly... Any help?!THANKS EVERYBODY FOR THE HELP! BUT WITH SOUND IT'S PREETY BETTER TO UNDERSTAND!!!
