A step-index fibre has a core index n₁ = 1.48 and cladding index n₂ = 1.46, in air.
| Question | Working | Answer |
|---|---|---|
| Numerical aperture | √(n₁² − n₂²) = √(2.1904 − 2.1316) = √0.0588 | ≈ 0.243 |
| Acceptance angle | sin⁻¹(0.243) | ≈ 14.0° |
| Critical angle at the core–cladding boundary | sin⁻¹(1.46 ÷ 1.48) | ≈ 80.6° |
Light entering within the acceptance cone is totally internally reflected along the core.
Two standard numericals.
| Question | Working | Answer |
|---|---|---|
| de Broglie wavelength of an electron accelerated through 100 V | λ ≈ 1.226 ÷ √V nm = 1.226 ÷ 10 | ≈ 0.123 nm |
| Grating spacing for 5,000 lines per cm | 1 cm ÷ 5,000 | 2 × 10⁻⁶ m |
| First-order angle for 589 nm light | sin θ = 589 × 10⁻⁹ ÷ 2 × 10⁻⁶ = 0.2945 | θ ≈ 17.1° |
The electron's wavelength is similar to atomic spacing, which is why electrons diffract from crystals.

Most lost marks come from unit errors and derivations with missing steps.
| Mark-loser | What to do instead |
|---|---|
| Mixing nm, µm and m | Convert to metres before calculating |
| Lines per cm used as spacing | Convert lines per cm to spacing d = 1 ÷ N |
| Derivations with skipped steps | Show each assumption and step |
| Unlabelled diagrams | Label rays, angles and components |
| Lab results without error analysis | Calculate percentage error and discuss sources |
| Formula without units | Give units with every answer |
Engineering physics is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| University exams | Derivations and numerical problems |
| Lab exams | Performing experiments and calculating results |
| Lab records | Aim, apparatus, observations, calculations and result |
| Internal tests | Short numericals and theory |
| Vivas | Explaining experiments and concepts |
Engineering physics labs use these instruments.
| Tool | What it is used for |
|---|---|
| Spectrometer | Grating and prism experiments |
| Travelling microscope | Newton's rings |
| Laser and optical fibre kits | Fibre optics experiments |
| Hall effect and four-probe set-ups | Semiconductor experiments |
| Excel | Graphs and error analysis |
Engineering physics is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where engineering physics is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | Physics modules in BEng degrees | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | Harvard or a journal style |
| United States | Physics for engineers courses | Letter grades A–F and a 4.0 GPA scale | APA, CSE or ACS |
| Australia | Engineering physics units | HD, D, C, P at university; ATAR for school leavers | Harvard or APA |
| Canada | Engineering physics programmes | Letter grades or percentages; GPA scales vary by province and university | APA or CSE |
| India | First-year B.Tech/BE engineering physics (AKTU, VTU, Anna University and others) and diploma courses | Board exam percentages; university CGPA, often on a 10-point scale | As your university specifies |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of engineering physics help depends on the number of problems and your deadline. A short numerical costs less than a full lab record. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Yes. Tutors explain concepts, derivations and numericals and help with lab records.
Physics applied to engineering, covering optics, lasers, quantum physics, materials and semiconductors.
A measure of an optical fibre's light-gathering ability: √(n₁² − n₂²) for a fibre in air.
The maximum angle at which light can enter the fibre and still be guided by total internal reflection.
When more atoms are in an excited state than in the lower state, which is needed for laser action.
Spontaneous emission happens randomly; stimulated emission is triggered by an incoming photon and produces coherent light.
Use λ = h ÷ p, or approximately 1.226 ÷ √V nm for an electron accelerated through V volts.
Interference between light reflected from the top and bottom of a thin air film between a lens and a flat plate.
