Waves Mistakes

Question 1

How to do the descirption of wave cycle

Answer 1

• mention how it moves if transversel
• oscialltes up down to max positve negative or rest disolacment
• WITH REFERENCE OF CYCLE OF WAVE (LIKE 1/4 ETC)

Question 2

When talking about minima for stationary waves

Answer 2

Mention swtsriknsry waves

• but the nodes always constant out of ohase
• so no motion there

Question 3

How is ciherent made from double slit

Answer 3

• s acts as a point source
• s1 and s2 come from same source goving same frequency and wavelentgh
• spoaths to s1 and 2 constant so constaly phase difference

Question 4

To calculate phase difference of two different but coherent waves how

Answer 4

Use times as an indicator for fraction if cucel. (If it takes 1s aPart and whole thing is 4s then 0.25 wl)
